This is a merger of ZeeRex and OpenSearch, with a major new feature
added. Both of those description languages describe how you can talk to
the service being described, but don't tell you how to interpret the
service's response. The underlying assumption in ZeeRex is that it is
describing an SRU or Z39.50 service and therefore doesn't have to
describe how to access the elements of the response. This new
description language specifies how to find SR elements in non-SRU/Z39.50
responses. The trivial example I provided shows how the description
language can be used for an SRU response. But it can also be used in an
HTML response.
If you think of OpenSearch as a description language for turning
existing user-oriented services into web services, then it only does
half the job. It tells a client how to construct the URL to talk to the
service, but doesn't describe how to interpret the response. We're
adding that second half. We've been loosely calling this new language
"OpenSearch on steroids".
This is a major component in a general solution to metasearching. With
this description language, you should be able to make almost any search
interface accessible to client searching.
