The SoCoRe! project (Open science for Conservation / Restoration of the cultural heritage) aims at structuring and opening data produced by the activities of conservation / restoration of the tangible cultural heritage. Supported by the Fondation des Sciences du Patrimoine, which gathers a very large scientific community in this field, the SoCoRe! project continues the effort, led by the foundation, of designing common models, vocabularies, platforms and tools for sharing conservation / restoration data. The goal of the SoCoRe! project is to build the tools for producing data that respects the common models, for storing, sharing and querying data produced by the community, and to specify the good practices and the procedures for implementing this approach for an open science.
