Abbreviations and Acronyms used in the literature

This alphabetical listing of abbreviations and acronyms was compiled by Barbara Shuh of the Interlibrary Loan Application Standards Maintenance Agency, as her personal aide-memoire for the multitude of shortened forms of names used in the literature discussing the ILL protocol. The coverage is wide but does not claim to be comprehensive. This first release of the list contains only a few hypertext links, but more will be added as time permits.

    FTP File Transfer Protocol Internet RFC 959: FTP can carry electronic documents encoded in ASCII or binary formats

    A protocol used to transfer files over a TCP/IP network (Internet, UNIX, etc.). It includes functions to log onto the network, list directories and copy files. It can also convert between the ASCII and EBCDIC character codes. FTP operations can be performed by typing commands at a command prompt or via an FTP utility running under a graphical interface such as Windows. FTP transfers can also be initiated from within a Web browser by entering the URL preceded with ftp://.

    Unlike e-mail programs in which graphics and program files have to be "attached," FTP is designed to handle binary files directly and does not add the overhead of encoding and decoding the data.

    IMAP Internet Message Access Protocol RFC 1730 (prior to IMAP4, published in Dec. 1994, standard was called the Interactive Message Access Protocol). A standard mail server expected to be widely used on the Internet. It provides a message store that holds incoming e-mail until users log on and download it. IMAP4 is the latest version.

    IMAP is more sophisticated than the Post Office Protocol (POP3) mail server. Messages can be archived in folders, mailboxes can be shared, and a user can access multiple mail servers. There is also better integration with MIME, which is used to attach files. For example, users can read only the headers in the message without having to automatically accept and wait for attached files to download that they don't want.

    Both IMAP and POP accept SMTP-formatted messages that have been routed across the Internet.

    ---FYI 18 Internet Users' Glossary

    A protocol used to access a directory listing. LDAP support is being implemented in Web browsers and expected that LDAP will provide a common method for searching e-mail addresses on the Internet, eventually leading to a global white pages.

    LDAP is a simplified version of the DAP protocol, which is used to gain access to X.500 directories. It is easier to code the query in LDAP than in DAP, but LDAP is less comprehensive. For example, DAP can initiate searches on other servers if an address is not found, while LDAP cannot in its initial specification.

    TIFF Tagged Image File Format De facto standard for document page images. Defines format of an image file by providing a set of well-defined tags whose values indicate essential information such as page size, resolution (dots per inch, dots per line, lines per page), colour encoding information, type of compression (CCITT, JPEG), etc. The inclusion of colour and gray scale information makes it suitable for many types of data other than text images.

    UNIverse   Large scale CEC project begun in 1996 which aims to deliver and utilise a logical union catalogue to deliver a library services for both the end-user and the librarian at a single point of contact for specific subject domains. It will include an ILL service integrated to the search process using the ISO ILL protocol over both TCP/IP and e-mail transports. Co-ordinating partner is Fretwell-Downing Data Systems Ltd.

    white pages See also: Knowbot, netfind, whois, X.500, InterNIC. The Internet supports several databases that contain basic information about users, such as e-mail addresses, telephone numbers, and postal addresses. These directory information databases can be searched to get information about particular individuals. Because they serve a function akin to the telephone book, these databases are often referred to as "white pages."

    1976 ITU standard for packet switching networks. Public X.25 communications networks have been available worldwide for many years, but they are typically limited to 56 Kbps and less. New packet-switched networks employ frame relay and SMDS technologies rather than X.25.
