The overall objective of the eCOTOOL project is to improve the development, exchange, and maintenance of VET certificates and their accessibility and transparency by harmonizing Europass with other European instruments (EQF, ECVET) and e-competences. This will increase the European mobility and transparency of VET systems and will be achieved through:1. The Development of an Application Profile and Technical Tools based on the Europass Certificate Supplement (CS) under the Brand "Europass CS eco-tools"2. The Adaptation of all Europass CS eco-tools to the Agricultural Sector and their Pilot Testing and Optimization the eCOTOOL project will provide advanced and sustainable instruments and tools for the Europass CS: First an application profile will be developed as an information model from the European instruments to achieve the European standard for certificate repositories based on the Europass CS specification. This information model will delivered with a full XML binding to complete the Europass CS eco-tools and to support and facilitate their dissemination to and application in all European countries. The CS eco-tools will be tested and evaluated by applying them to the agricultural sector. This pilot testing will be conducted according to the findings and results of a needs analysis conducted in this sector. Finally the CS eco-tools will be disseminated throughout Europe and in particular submitted to the European Standardization Bodies to launch an official European Norm (EN) initiative.The main benefits of the Europass CS eco-tools are:• Better accessibility to existing Europass Certificate Supplements by ensuring full interoperability amongst any given IT system• Easier development and maintenance of further Europass Certificate Supplements • Simple exchange of Europass Certificate Supplements between any online platforms and repositories • Enhancing European mobility by improving comparisons of VET solutions and their certificates.
