Invenio (formerly CDSware) is a suite of applications that provides the framework and tools for building and managing an autonomous digital library server. It complies with the Open Archives Initiative metadata harvesting protocol (OAI-PMH) and uses MARC 21 as its underlying bibliographic standard. Its flexibility and performance make it a comprehensive solution for the management of document repositories of moderate to large size.
ssqlfs uses a defined file/directory structure to generate an SQL database which corresponds to that file/directory structure. Along with support for one-to-many tables, ssqlfs includes support for representing many-to-many tables. Ideally, the filesystem would be interconvertible with an SQL database, but at this point the functions for generating a file/directory structure from the SQL database remain to be thoroughly tested.
TXR is a new data munging language. TXR's special pattern language provides template-based matching of entire documents or large sections of documents. It also contains a language for functional and imperative programming. It is written in C and takes the form of a utility that is portable to Unix-like platforms and Windows.
Treep is a simple language for doing symbolical computations. It operates on numbers and strings that can be organized in more complex objects. These objects are lists of name-value pairs that are stored in memory as AVL trees. It has about sixty built-in functions to operate on such data and a way to define new functions. Treep syntax very much resembles Lisp. The power of treep is its simplicity and security. Treep is a good tool do process objects and relations between them. For example it is possible to define graphs as a sets of vertices and edges in text file, parse that file, do any computations you like, write modified data to text file. Treep works well on graphs, trees, linked lists, simple hashes. Treep is not good at processing texts, dealing with system input/output.
