Anyone know anything about this?
We should make a stink about their non-support of CQL!

ProQuest XML Gateway
The new ProQuest XML Gateway introduces a next-generation level of support
for federated search applications. Federated search is of growing importance
in the library today serving as one of the primary means for resource
discovery. Recognizing this, ProQuest has invested in a new solution for
supporting federated search of our databases.
The new ProQuest XML Gateway, available November 2004, is a Web services
application that enables ProQuest customers and their vendors to send search
requests to and receive responses from ProQuest using XML technology. This
new solution provides convenience, flexibility and powerful search
capabilities to support your library's application of federated search.
Moving beyond limitations
ProQuest has long supported a Z39.50 interface as a means for libraries to
use third-party applications for search and retrieval of ProQuest content.
Today, many federated search vendors use Z39.50 to reliably support access
to ProQuest databases. While it has dutifully served in this role , the
Z39.50-based solutions entail overhead and limitations reflective of an
earlier era. The advent of new technologies and standards, such as SRW/U,
enables design of more streamlined and adaptive solutions. The introduction
of the ProQuest XML Gateway is such an innovation.
ProQuest does not plan to discontinue support for our existing Z39.50
interface. Future investments in enhancing automated access to the ProQuest
platform will be directed toward expanding the XML gateway rather than the
Z39.50 interface.
Flexibility to support advancements in federated searching
More flexible than a Z39.50-based interface, the XML gateway leverages the
powerful capabilities of the ProQuest search engine and makes them available
in a federated search environment. The ProQuest XML Gateway supports a full
spectrum of search features (e.g. limits, etc.) and queries ranging from
simple free-text searches to complex nested Boolean statements and proximity
operators. The opportunity is created for advancing the federated search
user experience.
The technology: A standards-based approach
With intentions consistent with ZING ( Z39.50-International: Next
Generation) to evolve from Z39.50 to a more mainstream approach, the
ProQuest XML Gateway is based on the SRW/U model and consistent with
objectives of NISO's Metasearch Initiative.
The SRU standard is applied for the access protocol and SRW XML schema types
are used for the search response, including diagnostics. The ProQuest query
language is engaged, rather than CQL, to fully leverage the power of the
ProQuest search engine in this initial release of the XML gateway.
Database products supported
The new ProQuest XML Gateway initially supports most ProQuest branded
database products and a few additional products, as summarized below.
* Traditional ProQuest databases including but not limited to
ABI/INFORM, ProQuest Research Library, ProQuest Discovery, PQ5000, ProQuest
Accounting and Tax, ProQuest Health and Medical Complete, ProQuest
<http://www.rose-net.co.ir/products/PRODUCTS1/UMI%5CPQcareer.htm> Career &
Technical Education, ProQuest Criminal Justice Periodicals Index.
* ProQuest Newspapers, including Canadian Newsstand and ProQuest
Historical Newspapers
* Micromedia ProQuest CBCA databases (Reference, Current Events,
Business and Education)
* ProQuest Diversity Databases (e.g. Ethnic Newswatch,
Alt-Presswatch), ProQuest Newspapers including Canadian Newsstand,
* American Periodicals Series
ProQuest Digital Dissertations (now "ProQuest Dissertations and Theses")
will be accessible via the gateway by year-end.
Third-party index products such as CINAHL, PsycINFO and ERIC will not be
supported by the initial release of the gateway although their companion
full text databases will, including ProQuest Nursing Journals, ProQuest
Psychology Journals and ProQuest Education Journals.
