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.
Nabu is a simple framework that extracts chunks of various types of information from documents written in simple text files (written with reStructuredText conventions, parsed with docutils) and that stores this information (including the document) in a remote database for later retrieval. The processing and extraction of the document is handled on a server, and there is a small and simple client that is used to push the files to the server for processing and storage. The client requires only Python to work. The presentation layer is left unspecified: you can use whichever Web application framework you like.
