The registered internet IP port for Z39.50 is 210.

These projects have a much lower barrier to entry for developers than the original Z39.50 protocol, allowing the relatively small market for library software to benefit from the web service tools developed for much larger markets. Want to map to Z39.50 easily Z39.50 has got a CCL regex attribute already. Both expect search results to be returned as XML. SRU is REST-based, and enables queries to be expressed in URL query strings SRW uses SOAP. The successors to Z39.50 are the twin protocols SRU/SRW ( Search/Retrieve via URL/ Search/Retrieve Web service), which drop the Z39.50 communications protocol (replacing it with HTTP) while still attempting to preserve the benefits of the query syntax. These attempts fall under the designation ZING (Z39.50 International: Next Generation), and pursue various strategies.

Z39.50 is a pre- Web technology, and various working groups are attempting to update it to fit better into the modern environment. The Bath Profile is maintained by Library and Archives Canada. Implementation of the Bath Profile has been slow but is gradually improving the Z39.50 landscape. This document rigidly specifies the search syntax to employ for common bibliographic searches, and the expected response of Bath-compliant servers. A third may have no name index and fall back on its keyword index, and yet another may have no suitable index and return an error.Īn attempt to remedy the inconsistency is the Bath Profile (named after Bath, England, where the working group first met in 1999). One server may have an author index and another may use its index of personal names, whether they are authors or not. This allows Z39.50 queries to be formulated without knowing anything about the target database, but it also means that results for the same query can vary widely among different servers.

For example, if the client specifies an author search using attribute 1003, the server must determine how to map that search to the indexes it contains. The syntax of Z39.50 is abstracted from the underlying database structure. In practice, the functional complexity is limited by the uneven implementations by developers and commercial vendors.

The syntax of Z39.50 allows for very complex queries. Search queries contain attributes, typically from the bib-1 attribute set which defines six attributes to specify information searches on the server computer: use, relation, position, structure, truncation, completeness. The protocol supports search, retrieval, sort, and browse.
