PROFMUS is a collaborative project that aims to carry out the research and consolidation of information to support further research about the Portuguese musicians active in the period from 1750 to 1986. The information to be collected must include as many relevant attributes as possible, especially about their academic background, professional careers, and personal details. This project considers a large amount of data from a wide time-period, which means there will be various attributes for each object, which will evolve over time or differ from source to source. There is also an issue wit the lack of uniformity of existing sources in multiple institutions, museums, archives, and databases, each with its own data scheme. Since PROFMUS has a long-term perspective, it does not try to create a uniform and prefixed scheme for the data to consolidate but accepts every different scheme and stores all data in a controlled knowledge base. We describe here an application for that purpose, using MediaWiki and Wikibase for storage, and a back-office specific application to manage and publish the data.
