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).
SiSU (Structured information, Serialized Units) is a lightweight markup based, text structuring and publishing framework (that features granular search). With minimal markup of a plaintext file, it produces: plain-text, HTML, XHTML, XML, ODF, LaTeX, PDF, and populates an SQL database at an object/paragraph level for granular searches. Prepare documents using your text editor of choice, then use SiSU to generate the desired output formats. SiSU is controlled from the command line.
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.
Samizdat is a generic RDF-based engine for building collaboration and open publishing Web sites. It provides users with the means to cooperate and coordinate on all kinds of activities, including media activism, resource sharing, education and research, advocacy, and so on. It intends to promote values of freedom, openness, equality, and cooperation.
NorfelloCMMS OS is a powerful CMMS application. It enables organizations to easily manage labor, equipment, and service requests via a Web-based interface. This leads to increased efficiency of labor usage and reduced time spent on maintenance tasks. It is targeted at any organization that handles maintenance tasks or has equipment to track. From maintenance management of heavy industry to management of computer network equipment, it can be customized to meet the requirements of various different domains.
Ruote is a workflow engine. It's a runtime for long running business processes. Processes are explicitly defined and may be explicitly handled (start, pause, cancel, update). A process is started by handing a business process definition to the engine. A process definition is expressed in ruote’s own process definition language, which comes in three flavours: XML, a Ruby DSL, and Radial. A process definition describes the flow of work among participants. A ruote engine can simultaneously handle multiple process instances, created from one or more different process definitions. A process instance can be modified on the fly.
