Landscape report on Metadata for SRC nodes capabilities, functionalities and policies

In some Olive and/or Architecture meetings we have commented about the need of having a metadata schema (common metadata description Language) to describe formally the site capabilities, functionalities, status of the resources, policies among others. Also metadata for describing the computational jobs. In other infraestructures implement an Information System with this metadata, and this system can be used for serveral things, one of them, for brokering resources.

Here we can explore some of the options:

•  https://www.commonwl.org/
• https://streamflow.di.unito.it/documentation/latest/architecture.html
• GLUE (Grid Laboratory Uniform Environment) Schema used in EGEE and WLCG to describe sites connected to the Grid Infrastructure. Also ARDA Metadata Grid Application (AMGA). They can be quite old, not sure if they are still supported.
• IVOA Provenance data model
