Template Data Interface (TDI, /ʹtedɪ/) is a markup templating system written in Python with (optional but recommended) speedup code written in C. Unlike most templating systems, TDI does not invent its own language to provide functionality. Instead, you simply mark the nodes you want to manipulate within the template document. The template is parsed, and the marked nodes are presented to your Python code, where they can be modified in any way you want.
Clipboard Modifier is a flexible system to modify the text in a clipboard in a variety of ways. It can copy a spreadsheet and change the clipboard so that it can be pasted into a wiki, with vertical bars (|) instead of tabs. It can modify multi-line clipboard text so that it can be pasted into Java or Python as strings. An URL in the clipboard pointing to Amazon can be modified so that it has your Associate ID in it. It can pipe the clipboard to a shell command and retrieve the output from it. A clibpboard can be forced to text, removing things like formatting. A complicated URL can be converted into its Python equivalent, using urlencode.
Isobel is a framework to build complex information retrieval and analysis systems. Isobel can be functionally divided in two subsytems, Isobel Gatherer (the crawling and filtering subsystem) and Isobel Analyzer (the analysis subsystem). The two subsytems can also be used separately. Isobel Gatherer offers ready-to-use services like content fetching, scheduling, document format conversion, Hyperlink graph storage and analysis, content storage and indexing. A programmer may easily add new services. Isobel Analyzer uses the IBM UIMA architecture to reuse the analysis components developed for this architecture.
