SUMMARY:

The Portfolio aims to support resource discovery, question banks, preservation and data access. Furthermore, it helps all Service Providers meet the Data Seal of Approval certification requirements related to metadata issues. Support to the description of data will go beyond the social sciences, as the Portfolio benefits other disciplines as well (for example, humanities and health sciences). Its support to multilingual searches and data discovery reflects the needs of both Service Providers and researchers. Moreover, the Portfolio would enable Service Providers to retain independence as well as to interact within an integrated CESSDA service, while at the same time contributing to the commensurability of metadata and building a well-functioning discovery system. The Portfolio includes core metadata model and controlled vocabularies (CVs) for relevant metadata fields, the latter enabling the implementation of the cross-language information retrieval systems. Whenever possible, existing CVs are used. The Portfolio covers study-level metadata and variable/question level metadata. It is standard based and compliant with Data Documentation Initiative (DDI), international standard for describing statistical and social science data. It is also extensible, enables updates and adaptations to changing functional requirements over time. The Portfolio Version 1 covers most urgent needs, primary it supports building of the Product and Service Catalogue and the Euro Question Bank. Deliverable 5 concludes Phase 1 of the CMM project by reporting the results of the impact analysis that was conducted by ADP. It also provides pathway for the further work on the development of the Portfolio in Phase 2 of the project.
