Xapian is a search engine library, scalable to collections containing hundreds of millions of documents. It's written in C++ with bindings for Perl, Python, PHP, Java, Tcl, C#, Ruby, and Lua. It is a highly adaptable toolkit that allows developers to easily add advanced indexing and search facilities to their own applications. It supports the Probabilistic Information Retrieval model and also a rich set of boolean query operators. Omega is a Web search application built upon the Xapian library. It can index a Web server's document tree (including HTML, PDF, OpenOffice, MS Word/Excel/Powerpoint/Works, WordPerfect, RTF, PS, etc.), or data exported from arbitrary sources (e.g. SQL databases).
Search::Xapian is a Perl XS frontend to the Xapian C++ search library. It is a fairly complete wrapper: most features of the Xapian library are made available for use from Perl. Xapian is a highly adaptable toolkit that allows developers to easily add advanced indexing and search facilities to their own applications. It supports the Probabilistic Information Retrieval model as well as a rich set of boolean query operators. It's fast and scalable to hundreds of millions of documents.
Finance-QuoteHist provides Finance::QuoteHist, a Perl module that provides easy fetching of historical stock quotes from a variety of sources on the Web. The bundle includes the underlying site-specific modules. Reliability is enhanced through the use of symbolic extraction provided by HTML::TableExtract along with automatic failover to alternate sites.
fastcgi-gallery is a Web gallery based on Apache::Gallery, but is hacked for usage with Perl FastCGI scripts. Therefore, this version is about 10x quicker (with cache turned on) than Apache::Gallery. With the best template system (Template-Toolkit) you can customize your gallery as you wish; for example, you can create a multi-language gallery. A database is not used; everything is stored in files. Output and generated thumbnails are cached for speed optimization.
HEBCI is a technique that allows a Web form handler to transparently detect the character set with which its data was encoded. By using carefully-chosen character references, the browser's encoding can be inferred. Thus, it is possible to guarantee that data is in a standard encoding without relying on (often unreliable) Web server/browser encoding interactions.
Net::Z3950::SimpleServer is a Perl module which implements the server side of the Z39.50 (information retrieval) protocol. It hides the complexity of network exchanges, packet serialization, and session handling. You are required only to implement simple callbacks to support searching and record retrieval. It is the basis of the "Zoogle" project, which is a Z39.50 gateway to the Google web index.
A Life Science Identifier (LSID) Resolver is a software system that implements an agreed LSID resolution protocol to allow higher-level software to be able to locate and access the data uniquely named by any LSID URN. This project is the first implementation of a Web service-based LSID URN resolution protocol, and includes Java J2EE, Perl, and Win32 COM/C++ client & server stacks, example programs, and tutorials on how to establish a LSID resolver for any organization.
