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).
Berkeley DB XML is a native XML database engine for use within your product. Made available as a C++ library with language bindings for Java, Perl, Python, PHP, and Tcl, it integrates directly into your application (it is not a standalone database server). It provides XQuery access into a database of document containers. XML documents are stored and indexed in their native format using Berkeley DB as the transactional database engine.
Eidetic is a middleware library for building database driven applications with Perl and Template::Toolkit. It provides handlers for displaying, editing, searching, and administrating data. It provides an interface-generic way of building db apps allowing Web, command line, or daemon styles of interfaces. It is currently used by several applications, including STP, docsys, and rackview.
Tk::Text::Viewer is a text widget that can display text files under TK. It enable the user to search text and navigate in a Text widget. The reason for creating this module is that it doesn’t require downloading of modules other that Tk, and a need for simple user interaction. The package includes a text viewer demo program that can be used as a stand-alone browser.
TCB::Library is a DBIx::Frame object written to keep track of library books at the TCB Group at UIUC. It provides a Web interface for adding books to the library, for users to check out and return them, and for reminder messages to be sent out periodically to list what books are checked out. This is actually a fairly basic function of research groups, but doesn't have a standard software package.
Cafeterra is a message queue-based EAI project with a Web user interface for designing, processing, and monitoring inter-application data flows. Supported connectors are based on an RDBMS, flat files (CSV, fixed length record, XML, HL7, HTML, etc.), LDAP, and SOAP, with others planned. The main features are message tracking and archival, joining different connectors, an internal scheduler, and raising the flow on events.
LDAPview is a Perl-based framework for doing LDAP directory based data management via the Web. LDAPview can also be described as a flexible HTTP-to-LDAP gateway framework with a focus on making data management tasks easier. It is not meant to be a replacement for any generic LDAP client. It should be seen as a complementary tool alongside generic LDAP tools. By not being completely generic, but still very flexible, LDAPview services can provide a more intuitive and productive user interface for managing LDAP directory data.
