I have completed my first draft of an article entitled "An introduction
to Search/Retrieve URL Service (SRU)". From the text:
This article is an introduction to the "brother and sister" Web
Service protocols named Search/Retrieve Web Service (SRW) and
Search/Retrieve URL Service (SRU) with an emphasis on the later.
More specifically, the article outlines the problems SRW/U are
intended to solve, the similarities and differences between SRW
and SRU, the complimentary nature of the protocols with OAI-PMH,
and how SRU is being employed in a sponsored NSF grant called
OCKHAM to facilitate an alerting service. The article is seasoned
with a bit of XML and Perl code to illustrate the points.
Comments and corrections are more than welcome.
