The mission of DYAS, the Greek Research Infrastructure Network for the Humanities, is:

• to support the Greek communities of humanities researchers in advancing their work using ICT and in exchanging knowledge and working practices
• to broaden the scope of and opportunities for research through the interconnection of various distributed digital resources
• to promote the access, use, creation and long-term preservation of research data, both primary and secondary, in digital form.
The services being developed by DYAS fall in four groups:
1. sharing digital resources through a set of data, person, metadata, vocabulary and software registries
2. support for resource development, through a series of guidelines and specialized tools
3. contributing to DARIAH services, by participating in specific tasks of the Virtual Competency Centres
4. a digital humanities observatory to support continuous monitoring and recording of the advances in the field and to undertake dissemination actions.
