Pelagios is a community-driven initiative that facilitates better linkages between online resources documenting the past, based on the places they refer to. Our member projects are connected by a shared vision of a world in which the geography of the past is every bit as interconnected, interactive and interesting as the present. Pelagios has been working towards establishing conventions, best practices and tools in several areas of "Linked Ancient World Data": i. Linking and aligning of gazetteers. Gazetteers are the primary knowledge organization mechanism in Pelagios. In order to foster integration of gazetteers from different communities, we have been developing an RDF profile for publishing gazetteer metadata as Linked Open Data. ii. Tools to aid linking. To simplify the process of linking documents to the places they refer to, we have developed an Open Source geoannotation platform called Recogito. iii. Tools to visualize and navigate. To make the growing pool of data in Pelagios more accessible to everyday, we are working on a search engine called Peripleo. Peripleo will allow the navigation of the interconnected gazetteers that form the backbone of Pelagios, as well as the objects and documents that link to them. iv. Infrastructure for re-use. Data created in Recogito is available under CC terms for bulk download. Peripleo will feature similar capabilities and, in addition, offers a comprehensive JSON API to enable re-use in 3rd party applications and mashups.
