This article presents a work-in-progress version of a Dublin Core Application Profile (DCAP)
developed to serve the Social and Solidarity Economy (SSE). Studies revealed that this
community is interested in implementing both internal interoperability between their Web
platforms to build a global SSE e-marketplace, and external interoperability among their Web
platforms and external ones. The Dublin Core Application Profile for Social and Solidarity
Economy (DCAP-SSE) serves this purpose. SSE organisations are submerged in the market
economy but they have specificities not taken into account in this economy. The DCAP-SSE
integrates terms from well-known metadata schemas, Resource Description Framework (RDF)
vocabularies or ontologies, in order to enhance interoperability and take advantage of the benefits
of the Linked Open Data ecosystem. It also integrates terms from the new essglobal RDF
vocabulary which was created with the goal to respond to the SSE-specific needs. The DCAPSSE
also integrates five new Vocabulary Encoding Schemes to be used with DCAP-SSE
properties. The DCAP development was based on a method for the development of application
profiles (Me4MAP). We believe that this article has an educational value since it presents the
idea that it is important to base DCAP developments on a method. This article shows the main
results of applying such a method.FCT -Fundação para a Ciência e a Tecnologi
