HyperSQL is like the doxygen program with Javadoc added, but for SQL. It hypermaps SQL views, packages, procedures, and functions to HTML source code listings, and it shows all the code locations where these are used. You can use JavaDoc-style comments for documentation and even embed UnitTests with them.
XPath Methods allows XPath queries on ParsedXML XML documents (and possibly other DOM implementations) in Zope. XPath is a relatively simple but still quite powerful query language used to address portions of XML documents. When you call an XPath Method you will retrieve a set of DOM nodes which you can then display in a Web page using DTML or ZPT, or which you can issue operations upon using, for instance, Python scripts.
SWISH stands for Simple Web Indexing System for Humans. With it you can index directories of files and search the generated indexes. Based on EIT's swish, this is a cleaner-compiling, enhanced version with better docs, better installation and configuration tools, more sample configurations, and a Web page to help manage index rebuilding. SWISH is used with w4ais as a Web-based front end.
w4ais is a gateway between a forms-capable Web browser and an indexing/search program, based on the old EIT wwwwais program. This new version is tested completely with swish 1.2 and above, and should still work with freeWAIS. This version allows easy and thorough customization of the search page look and feel, and includes help and various utilities to install and configure multiple interfaces for various users or sites on a single system.
The Astro::ADS module is an OO Perl interface to the Astrophysics Data System (ADS) abstract service. The ADS is a NASA-funded project whose main resource is an Abstract Service, which includes four sets of abstracts: astronomy and astrophysics, instrumentation, physics and geophysics, and Los Alamos preprint server.
