MyCoRe is an established repository software framework in the German-speaking region. The open source framework is able to serve as basis for digital libraries, multimedia archives, research data repositories or institutional repositories. The name, pronounced "my core", indicates that there is a software core that can be used in custom applications. More than 80 MyCoRe applications are running at over 20, mostly German locations. They provide publications, digital objects (such as documents, manuscripts, books, catalogs, journals, newspapers, etc.) and research data. All objects are described with metadata. Also image files, sound documents, and videos may be included in MyCoRe-based information systems. The MyCoRe framework provides the functionality necessary to manage, store, present, and share metadata and digital resources. Various interfaces are supported. Resource harvesting within the OAI-PMH framework is provided. The deposit of content is possible via SWORD protocol (v2). ORCID identifiers are integrated in MyCoRe repositories for author identification and automated data export to or import from ORCID is possible. The support of schema.org and JSON-LD is the newest software development. Examples of MyCoRe applications are "DuEPublico" with the university bibliography at the University of Duisburg-Essen, the publication server of the TU Braunschweig or the "Digital Library Thuringia (DBT)".
