Freebase "is an open, Creative Commons Attribution (aka CC-BY) licensed collection of structured data," and a "platform for accessing and manipulating that data" via API. Almost 40 million entities and assertions about those entities are stored within a graph database. The database was built by pulling in open data and relies on community contribution to stay updated.

HEURIST (http://HeuristNetwork.org) is an extremely flexible, end-user oriented, web-based data management system designed specifically for Humanities data. Developed since 2005, it has been in active use across many projects since 2009. It is available both as a free web service for researchers (hosted at the University of Sydney Data Centre) or for installation on a physical or virtual server (Open Source on gitHub).
Researchers can design, create, manage, analyse, visualise and publish their own richly-structured database(s) through a simple web interface, without the need for a programmer(s). Quite complex databases can be built in a few hours by borrowing structures and vocabularies published by other users. Databases can be designed and built incrementally, as existing data are not affected by changes in structure. Databases created by Heurist are stored in MySQL with a repeatable structure facilitating independant access by other software.
Advanced features include record linking, graph structure, drill-down facet searches, rule-based queries, custom reports, linked map-timelines, network visualisation, normalised spreadsheet import, crosstabulation, XML feeds, XSLT transforms. The team provides initial email and skype assistance for project setup at no cost, and special customisations at modest cost.
