The KiWi core system is a flexible platform for building different kinds of semantic social software applications on top (currently the Semantic Wiki and the TagIT application). It provides all the core services required in such applications, like editing and tagging, the storage of content and associated meta-data, its own triple store, transactions and versioning over content and meta-data, a linked open data server, and many small features semantic social software developers will like (like convenience services for working with ontologies or SKOS thesauruses, etc.).
FECpp is a C++ library implementing a fast forward error correction code, sometimes also called an erasure code. These codes are used to split input data into a set of n shares, with the property that if any subset of at least k shares survives, the original data can be recovered by the decoder. The number of share losses the code will tolerate can be parameterized during encoding, allowing the code to be adapted to to a variety of loss scenarios. FECpp is bit-for-bit compatible with several other FEC libraries.
