The bits and pieces that make up Elog.io is in our
Github, but specifically
the following pieces make up the whole:
- Elog.io Browser Extensions - a single repository from which we build both Firefox and Chrome extensions with shared code between them (GNU GPLv3)
- HmSearch - a C++ implementation of a hamming distance search algorithm (MIT license). We also provide Node bindings for HmSearch. Master branch works against a Kyoto Cabinet backend, but branches exist for working against LevelDB or PostgreSQL. We currently use PostgreSQL as our own backend.
- Commons Hasher - our script that reads database dumps from Wikimedia and retrieves information from the Wikimedia API, as well as calculate hashes of images retrieved (GNU GPLv3).
- Catalog - our catalog infrastructure, that provides the API which the browser extensions communicate with (GNU GPLv3).
The catalog API is documented
with Apiary and we encourage you to check it out. Please do note that while
the API supports user profiles and extensive information about works, we
currently only make use of the API calls that lookup and provide information
about works and which do not require authentication.
Information about the photographs in the catalog is carried within
on Github that's a good starting point for learning how to communicate with
