Integrating Digital Epigraphies (IDEs) is a metadata and bibliography aggregator for Greek epigraphy, providing alignment and discovery of inscription references across multiple collections.
From the project website (archived 2017-09-20):
IDEs aims to bring a variety of resources for Digital Epigraphy together into a single browseable interface and to build APIs that support linking together epigraphic projects.
