This is a revised version of a paper presented at the annual conference of CIDOC, the Documentation Committee of the International Council of Museums (ICOM) held at the National Museums of Kenya, Nairobi, on 26th September 1996. The audience contained some people who were very familiar with the Internet and others who had never used it, so this paper gives an introductory overview of the kind of resources which are available as well as referring to a few specific items as examples of interesting applications. Other papers presented at the meeting discussed the impact of the Internet on museums in general and on museums in Africa in particular, and there were live demonstrations throughout the conference. As lists of museum resources on the Internet already exist, this paper provides links to some of them, without duplicating their content.

[Where I have found that links in this paper have become invalid since it was written I have updated them when possible. I have not updated the content, however, and some of the resources and projects referred to may no longer be current or not the best of those now available. - Leonard Will, August 1998.]

The headings of this paper are:

  1. The Internet throughout the world
  2. Principal Internet services
  3. Resources of use to museums
  4. Collaborative projects
  5. The Internet within a museum

The Internet throughout the world

--------------------------------------------------------------

Statistics

There are many surveys of the size and growth rate of the linked network of computer networks which we call the Internet; a collection of various sources giving statistical, geographical and other information about the Internet is given in Geography of cyberspace and in the Yahoo page for Internet statistics and demographics

Any statistics are rapidly out of date, but one estimate by Network Wizards is that in July 1996 there were over 12.8 million host sites and that the net continues to double in size approximately every 12-15 months: this corresponds to a growth rate of 5 to 6% per month. There is no way of telling how many users there are per site.

WWW pages from several hundred museums were listed on the Virtual Library Museums Pages (VLMP) in mid-September 1996, and the number was growing by at least one new museum site every day. The VLMP pages have been visited almost three-quarters of a million times during the two years they have been available, and they are now receiving over 1500 visitors per day. Many of these visitors will be museum professionals, but the numbers will also include non-museum people looking for museums to which they can pay virtual, and perhaps also real, physical, visits.

Availability

International connections to the Internet exist in 186 geo-political entities (presumably they are called "entities" to avoid the difficulty of defining what is meant by a country) and there are 51 entities which do not yet have connections, according to a survey published in June 1996 by Lawrence H. Landweber and the Internet Society and available by FTP from the University of Wisconsin. Even when there are some connections in a country, it may not be easy to obtain access, for reasons which include: The Internet itself is a significant force in helping to overcome all these problems. It creates social and commercial pressures for change, and spreads technical knowledge which helps people to overcome difficulties. The Internet still retains much of its original culture of colleagues working together to help each other, and although there are more commercial organisations on the Internet now they still provide a great deal of information without charge. The quantity of information, and the range of topics covered, are increasing daily. Most of what I know about the Internet I learned from the Internet itself.

Connecting to the Internet

Within each country, connections are provided by organisations called Internet Service Providers, who provide centralised switching equipment connected to international lines and other networks. These Service Providers include academic or government networks, commercial services and non-governmental organisations; those available in Nairobi include the African Regional Centre for Computing, Form-Net Africa and Africa Online. The Network Startup Resource Center (NSRC) contains a database about international networking developments and a large list of connectivity providers, with its major emphasis on countries in Asia, Africa, the Middle East, Oceania, and Latin America. The NSRC also provides help with obtaining software and setting up network services.

There is a logical inconsistency in saying that you can obtain the information you need to set up a network connection from the Internet itself, but there are many books and periodicals which give enough basic information for you to get started. It is still probably best, though, to start by speaking to someone who already has a connection, and to check the particular features provided by Internet Service Providers in your locality, because service providers are by no means all the same and the software and hardware you need might depend on which you choose.

--------------------------------------------------------------

Principal Internet services

--------------------------------------------------------------

Many different types of software, with clever and curious names, have been used or proposed for use on the Internet as it has developed over the past few years. We have ActiveX, Archie, Java, Jughead, Gopher, Hyper-G, Telnet, Veronica, WAIS, the World Wide Web and Xanadu. Some of these systems are obsolescent, some are still in the development stage and some are the current mainstream systems.

From a user's point of view, though, it is best to think of the Intenet as providing three main services like those we find on the main street of any town: "the Post Office", "the newsagent" and "the library". In future the Internet will fill some of the roles of "the department store" (electronic commerce), "the cinema" (video on demand) and "the museum" (virtual reality), but these applications are still somewhat experimental and I shall not discuss them in detail.

"The Post Office": electronic mail

Electronic mail, or "e-mail", is one of the earliest and simplest applications, but it is still perhaps the most used. It does not need an advanced computer or a fast modem, but it allows people to work together regardless of the bounds of distance and time. It combines some of the best features of the telephone and the fax machine with the ability to send messages in machine-readable form which can be edited and printed by the recipient. Many of the arrangements for this CIDOC conference were made by email, and it would have been a lot more cumbersome and expensive to do it in any other way.

An important additional feature of email is the ability to send attachments to mail messages. These can be any kind of computer data, including formatted word-processor documents, images or programs. Modern e-mail programs using features such as MIME (Multipurpose Internet Mail Extensions) deal with the processes of converting these binary files into printable characters for transmission over email links and converting them back to binary form again on the receiving machine, without the users having to bother about how it is done.

There are directories and lists such as the Infospace "White pages" service, the "Internet Address Finder" or "WhoWhere" which can be used to find email addresses for people and institutions. For museum professionals there is the MDA UK Museums e-mail Directory and the International email directory for museums maintained by Lawrie Conole from Australia but mounted on a Museum Computer Network site in the United States. This list is rather out-of-date at the time of writing.

Mailing lists

As well as personal mail, the post office also brings us circulars and junk mail of various kinds from mailing lists, and these too have their electronic equivalents. At least with electronic mail it is easy to delete items we don't want, especially if they are given meaningful subject headings (it's generally safe to delete anything with a heading in capital letters followed by a row of exclamation marks). Some mailing lists are very useful, though, and I shall discuss these in the next section.

"The newsagent": Newsgroups and mailing lists

Newsgroups and mailing lists are very similar in the way you use them; they are both like the letters columns of specialist newsletters, with an active and public exchange of views between people interested in a topic. The difference is in the way they are delivered: newsgroup items are distributed and stored on service providers' machines; anyone can read them there or transfer them to their own computer. Mailing lists hold central lists of names and e-mail addresses of people who want to receive them, and their messages are sent by private e-mail to each member of the list. Each of these types of distribution mechanism may be moderated; in this case contributed messages are scanned by someone to check that the content is appropriate for the list before it is distributed to all the subscribers.

There are over 17,000 newsgroups and thousands of mailing lists currently available. A useful selective list is Diane K. Kovacs' Directory of Scholarly and Professional E-Conferences. Other directories of mailing lists include the Liszt searchable list of 63,200 lists from 2017 sites (numbers as at 29th October 1996), and those maintained by Tile.Net or CataList; these latter two are limited to lists which use L-Soft International's Listserv software package, but this includes many of the useful ones (9430 lists at 31 October 1996). Information about lists dealing with museum topics are given on the ICOM site and on a site maintained by the Overall Knowledge Company in New York.

"The library": accessing information stored on the Internet

The World Wide Web (WWW)

Like personal mail, circulars and newsletters are delivered to our homes and desktops once we have decided to subscribe, without our having to collect each item as it becomes available. A great deal of information on the Internet, though, requires us to take action to fetch it ourselves, making an electronic visit to where it is held in the same way as we might make a physical visit to a library or bookshop. The software which is used for this is now predominantly a World Wide Web browser, the two leading versions being Netscape and Microsoft Internet Explorer. Various other software packages are available, some of them supplied by Internet service providers who may require the use of their proprietory software to connect to their services.

Although the trend is very much towards graphical interfaces with lots of pictures and diagrams, this is not necessarily an advantage. The amount of data required to represent an image is much greater than the equivalent area of text, and images therefore take longer to download and occupy more disc space. Many of the images now used in WWW pages do not add to the intellectual content, but are just logos or fancy type styles of something which could be more efficiently be presented in words. It is possible to configure a browser interface to receive only the text and not the images, but unfortunately some pages use images for menus without a textual alternative. There are many documents available on the WWW giving guidelines on good style, such as that from Tim Berners-Lee, Director of the WWW Consortium, the Sun Guide to Web Style or the Web Style Manual by Patrick J. Lynch at the Yale Center for Advanced Instructional Media.

For people who do not have, or prefer not to use, a graphical interface, there are pure text mode browsers available, such as Lynx, obtainable free of charge by FTP in versions for Unix and for MS-DOS.

WWW extensions

While some of the extensions which are being used with the WWW are just gimmicks which take time and space (and often cost users money as a result), other developments are potentially of great value in a museum context -- being able to show images of objects, for example. Animated graphics may be helpful in explanatory diagrams, and developments such as Java and ActiveX allow small programs, or "applets", to be downloaded to a user's computer along with a Web page. These can provide some local interactive functions such as selecting from data or presenting different views or formats without having to communicate with the remote computer for each command. Many examples are accessible from the Gamelan site. One project which illustrates what can be done is the U.S. National Library of Medicine's Visible Human Project, which allows you to choose and examine cross-sectional slices through a human body in three planes. Another is the Virtual Stonehenge, which presents images of the monument which you can move in, over and around; you can also change the date represented to one of several points between 8500 B.C. and 2000 A.D. This was produced by a collaboration between Intel, English Heritage and Superscape Virtual Reality, and requires the downloading of Superscape software. [The Virtual Stonehenge software page has been removed from the Internet site. The above link leads only to a descripton of it. - March 2000]

A good example of a museum site which uses Java to provide interaction is the Cheekwood Museum of Art, which allows the exploration of some of its paintings, bringing up commentaries on interesting details as they are found and pointed to.

Security

The fact that to use these facilities we have to download programs should make us wary. It is always good practice to have a system backup before running a new program, and when you receive Java or ActiveX applications you may not even be aware that you are doing so. Although they include measures to safeguard users from faulty or malicious programs, no software should be trusted as infallible. Various systems of encoded signatures and certificates are being developed to identify sources which can be "trusted", but these are not yet widely enough understood and used for them to be particularly helpful. Other security aspects relate to maintaining confidentiality and to the safe transfer of money on the Internet, but these are outside the scope of this paper.

Caching and proxy servers

It is important to use the Internet efficiently, both so that you do not clog up lines with unnecessary or repetitive traffic, and so that you keep your telephone costs down when using a dial-up connection where you have to pay per minute. One of the most helpful ways of doing this is by using "caches" or "proxy servers". These are places to which you can have rapid access and where web pages can be stored so that you don't have to fetch them from distant sites when you want to see them again. Caches may serve a whole country, a particular group of users (such as the customers of one Internet Service Provider), an institution such as a museum, or a single user. One useful caching program which you can run on your own machine is NearSite; this will not only capture pages as you view them, so that you can browse them off-line later, but it also maintains a file of bookmarks, lets you search through pages you have captured, and lets you pre-specify pages or sites you want it to fetch automatically the next time you connect.

FTP (File transfer protocol)

Some of the information stored on the Internet is not in the form of World Wide Web pages. There are documents in plain text, in various word processor formats, and in document exchange formats such as Adobe Acrobat or Envoy [Envoy is no longer being developed or marketed, though the viewer software is still available - August 1998]. There is also a great quantity of software which you can download to your computer in binary form. These resources are normally transferred using "File Transfer Protocol" (FTP), which is a way of moving data from one computer to another even though it is not limited to printable characters. Modern WWW browsers incorporate FTP facilities, so that when you need them to do so they display a separate window to manage the file transfer process. There are also separate FPT programs and such as WS_FTP which give more control of the transfer process and may be needed if you want to upload files to a remote site, as when storing your own WWW pages on a server run by someone else. The traditional program for finding the location of files in FTP sites, when you know the file name, is Archie, but Web-based systems such as FTP search and its simple front-end Filez, are now available and are easier to use.

Use of mail to fetch WWW and FTP pages

If you have only an electronic mail connection to the Internet rather than a WWW browser, you can still obtain much of the information on the Web. A useful document describing services which will retrieve information for you and send it to you by email is available from various sources, including the news.answers pages at MIT or the Mailbase site in the UK.

--------------------------------------------------------------

Resources of use to museums

--------------------------------------------------------------

Resources of interest to museums fall into three categories:

There are lists and guides to all of these kinds of resource already on the Internet, so I shall indicate here only the kinds of information which is available without duplicating the lists. Lists which give details and links include:

Types of resource

Museums use many different styles in presenting their collections in their Web pages, as they do with printed publications. Some have aimed for coverage, including a high proportion of their collections even though most items may not be given more than a brief textual description. Examples of these are the Hampshire County Council Museums Service and the Edinburgh University Collection of Historic Musical Instruments. Others give a more "glossy" presentation of a selection of their collections, of special exhibitions, or of "highlights" complete with pictures and interpretative text, as is done for example by the Detroit Institute of Arts and the British Museum.

Some museums provide searching facilities so that you can retrieve records of items by subject, name, place or date, while others classify their material into groups to help you to focus your browsing. Both approaches are desirable, and some provide both, though a good searching system gives you the flexibility of creating your own groups as you search. Some go even further and allow you to make a "virtual visit" to the museum. This may take the form of a real or imaginary map showing parts of the museum you can visit, or may contain real or computer-generated pictures of the museum building. Good examples are the National Museum of American Art and the Finnish National Gallery

The Berkeley Museum Informatics Project has gone even further than this, and in their "Mechanical gaze" project they experimented with a system which allows you to control an on-line camera in a gallery, so that you can move around a group of selected objects and choose your own viewpoint of each of them. They are also trying out a system of cameras and microphones mounted on free-flying miniature airships or "blimps" which can be piloted remotely over the Internet. [The web pages giving access to these proejcts are no longer available - March 2000]. This is perhaps as near as we can come to the concept of a virtual museum visit, until someone develops a working Star Trek type of matter transporter to let us send real objects along telephone wires.

Other forms of interaction can be provided without needing to create physical movements in the host museum (apart from the read/write heads of its computer's disk drives). It is possible to have interactive exhibits such as those provided in science centres: the Association of Science-Technology Centers has a tour guide to these.

There is no clear boundary between museums, art galleries, archives and libraries, and all these types of institution are now accessible on the Internet. The archivists are using SGML to develop finding lists for their collections, as well as having added to the bibliographical MARC formats to meet their needs. These systems make many options possible for searching and formatting. The Encoded Archive Description project at the University of Berkeley is one of the leading developers in this area. The library community has long provided remote access to computerised catalogues, and many of these are now being converted to provide WWW interfaces. Library and archive work can be traced through the library and archive pages of the WWW Virtual Library, as well as through service such as the Bulletin Board for Libraries (BUBL) or the Web pages associated with the Archives and Archivists e-mail list.

Standards, resources and services for use by museum professionals

These include documents and papers, standards, reference works, data models, directories, terminology lists and thesauri, commercial information about the features and availability of products and services, and support and upgrades for software and publications. Lists of these can be found on the pages of CIDOC itself, the Museum Documentation Association, the Getty Information Institute Berkeley Museum Informatics Project and the Museum Computer Network.

Indexing and cataloguing services

There are many services which claim to index the whole Internet, or large portions of it; well-known ones are AltaVista, Infoseek, Excite and DejaNews. These work in different ways and have different strengths. Lists of these search services, with comparisons and evaluations, are given at the Webmaster's guide to search engines, a Robot-Driven Search Engine Evaluation Overview by Gillian Westera, and a Benchmark [test of] Five Search Robots by Dr Martijn Hoogeveen.

Starting points for lists of resources arranged by subject are the WWW Virtual Library, Yahoo and the Clearinghouse for Subject-oriented Internet Resource Guides

Access in different languages

The great majority of the information on the Internet is in English, but there is a significant amount in French and other languages using the latin alphabet. The CIMEC, the Information Centre for Culture and Heritage, in Bucharest, Romania, for example, has provided information about Romanian museums in Romanian as well as English; the special characters required can be viewed using standard browser software, so long as it is switched to an appropriate character set. As the use of the Internet spreads throughout the world, efforts are being made to overcome the problems of representing other languages, especially when they use character sets different from plain US ASCII. The development of the ISO 8859 series of character set standards, MIME and Unicode are aspects of this work. A review is given in Non-western Character sets, Languages, and Writing Systems

--------------------------------------------------------------

Collaborative initiatives

--------------------------------------------------------------

There are several projects in which museum organisations are working together to develop standards and techniques and to make their resources more widely and easily available. Some of these projects are listed below, with descriptive information extracted or summarised from their publications and Web pages.

Aquarelle: the Information Network on Cultural Heritage

AQUARELLE is a research and development project coordinated by ERCIM (the European Reseach Consortium for Informatics and Mathematics and supported by the European Commission, (Telematics Applications Programme, Information Engineering Sector, 1996-98 Contracts, Project IE 2005.) Participants are twenty-four cultural organisations, publishers, information technology companies and research organisations from several countries of the European Union. It aims to allow museum curators, urban planners, commercial publishers and researchers to collect information they need from wherever it is located. It will give them facilities to store collections of information in "folders", which will be available for searching and browsing on a network of connected servers. It will be possible to issue queries to the system without knowing in advance which of the participants has the required answers. It will explore multi-lingual information retrieval and will combine specific search facilities with broader "browsing" approaches.

The Consortium for the Computer Interchange of Museum Information (CIMI)

The CIMI Consortium consists of 16 organizations who have agreed to work cooperatively to solve complex problems relating to the electronic interchange of museum information. CIMI's major focus of effort is project CHIO, a demonstration project on the theme of folkart. It demonstrates online access to cultural heritage information held in multiple databases independent of the hardware and software used to store the data or search for it, showing the benefits of using two international standards cited in the CIMI Standards Framework: SGML and Z39.50.

HERINET

This is part of the international G7 program "Multimedia Access to World Cultural Heritage". The summary of its aims reads as follows:
"The project will realize easy infrastructures to access the cultural heritage documents by multimedia technologies summarized in virtual directories containing information, on nested levels of search, on fine arts in museums and archaeological sites. Aimed to both scientific and educational purposes, with particular reference to conservation, restoration, and technologies for easy and non-time-consuming operations for cataloguing material, is particularly devoted to problems related to disabled people and multilingual users."

NISAH Networked Information Sources in the Arts and Humanities

This project began with a meeting, held in February 1995 in Santa Monica, California, of representatives from projects and institutions building electronic databases of resources in the arts and humanities in the United States, Canada, and the United Kingdom. "Participants identified the mission of the project as follows: It was agreed that as a start the participants would write Issue Papers describing the present and future content, scope, access methods, and problems of their databases so that a clear picture of their purpose and scope would emerge, leading to consideration of the scope and limitations of the knowledge base they collectively represent. The Issue Papers would then be synthesized to determine the issues and problems associated with working toward a more integrated, coordinated presentation of these databases as part of a decentralized but comprehensive knowledge base for the arts and humanities. The goal for completion and synthesis of the Issue Papers, and their mounting on the participants' web sites, was November 1995. Some papers are now available on the NISAH project site but the synthesis does not appear to be available yet.

Remote access to museum archives (RAMA - Brameur site) and RAMA (Italian home site)

The RAMA Project (Remote Access to Museum Archives) is one of the major initiatives in Europe sponsored by the Commission of the European Union under the RACE Programme (Research on Advanced Communications for Europe). Its main goal was to offer validated services to users through telecom networks on the basis of the Distributed Multimedia Databases belonging to the museums, and with "just a single manual for all museums in Europe", regardless of the database contents infrastructure among other issues. The main challenge was to face the real problem of interconnecting heterogeneous environments, such as museums of different nature (different object registration cards for Archaeology, Fine Arts, etc), different museum archives operating over Database Management Systems (DBMSs) of different vendors and with different and pre-orchestrated internal data structure (even in the case of common vendors), and different LANs operating under Software of different vendors, in order to offer the information retrieved through a common client/server application via Internet. The project has been user driven in such a way that the users validate all the stages of the project, thus ensuring the final acceptance of the products.

The RAMA services for museums (Information Provider Sites) are supported by an open, scalable, and interoperable multimedia system architecture, implemented on the bases of a low cost equipment set (clients being Window PCs). Servers operate under UNIX, to ensure openness and interoperability. Full compatibility among different databases is ensured by the generation of a Common Query Mechanism, which is translated into the site Query Language by a suitable formatter/parser.

The RAMA services are currently installed as preoperational via Internet at the RAMA participant museums an pilot user sites, as well as at about 20 museums elsewhere in Europe and the US. Currently, the RAMA Consortium is founding the IMIN (International Museums Information Network) as well as an exploitation company called Museums On-Line with US and European shareholders to deal with support, software maintenance, new services and product development, and museums network management. IMIN and Museums On-Line are two complementary bodies that, with the support of Public Network Operators (PNOs) in Europe and the Commission of the European Union, widely spread the RAMA results with a clear purpose of the exploitation of multimedia services for museums throughout the world.

[Information on RAMA extracted from abstract of: Telemuseum services via Internet: present and future / by Guillermo Cisneros, Jesus Bescos and Jose M. Martinez. Information Services & Use, vol.16, no.02, 1996, ISSN: 0167-5265, p.81-101.]

--------------------------------------------------------------

The Internet within a museum

--------------------------------------------------------------

Strategy for museum information systems

In deciding their policy for Internet activities, museums should consider them in the context of their overall information systems strategy. This should not only cover the preparation of material targeted at fellow professionals, the general public, children, and special interest groups, but should also consider how Internet facilities can be provided and used within the museum itself. Aspects which need to be discussed include:

All these points are regularly debated on the Internet and there are many papers describing how other insitutions have dealt with them.

Involvement of museum staff

The Internet can make a major contribution to the public image and face of the museum, and can make its collections and resources known and used by a world-wide audience in a way which was never previously possible. It is important that all museum staff should be aware of this, should be encouraged to make their contributions and to take advantage of the benefits which the Internet brings.

Input will be required from staff with functions in documentation, education, interpretation, library and information services, computing, design, public relations, marketing and publications as well as those in curatorial departments. They should be see the Internet as another tool which will enhance, but not replace, their traditional activities. It is important that appropriate work on the Internet should be recognised as valid professional activity, and that, for example, electronic publications should be taken into account in assessements as well as those published in printed journals.

There may be opportunities for museums to develop new services based on their Internet presence, such as remote enquiry-answering services, news services on the subjects they cover, on-line booking for events and party visits, distribution of publications and images (free or for a charge), on-line shopping services and opportunities for advertising and sponsorship. It is for each museum to assess the possibilites and decide which will make a contribution towards its mission.
