3 weeks ago Dear Mario,
I think I understand the problem. You are delivering data via services (OGC) instead of data objects (dataset) and unfortunately F-UJI exclusively was built to support data objects. I know the difference seems to be subtile but this explains the results.
On the other hand, some major standards such as DCAT or ISO no not differentiate much between data and their transport methods. So this might justify changes to F-UJI.
I could therefore imagine to implement an additional test which checks for two service specific metadata properties: protocol and service endpoint In your example, this is specifically (and well) described using gmd:transferOptions which would provide the necessary metadata and instead testing for file size and file type F-UJI could test for the presence of these properties.
I know that currently GeoInquire and e.g. FAIR-EASE are trying to improve FAIR for GEO. Are you also involved via EPOS? It would be good to solve this issue within a broader community..

Description
We are trying to improve the evaluation of the following two DOIs:
In addition to DataCite metadata associated to the DOIs, we provide TC211 metadata, respectively:
Data from both can be downloaded using Open GeoSpatial Consortium (OGC) web services standards:
These standards support multiple data encoding formats, the user may request any of these supported formats, and may even apply a custom filter reducing the amount of data returned by the web service.
The "FsF-R1-01MD - Metadata specifies the content of the data" check seems to expect a "file type" and a "file size" but there is no way to provide it as in the case of web services many output formats are supported, and the size of the data output may vary depending on a combination of the selected output format and the presence of a data filter.
Expected Behavior
If web services are mentioned in the metadata to download data, the check should fully pass anyway, it does not matter if file type and size are not declared in the metadata.
Actual Behavior
The "FsF-R1-01MD" complains because neither the "file size" nor the "file type" information are specified in metadata.
Possible Fix
The "FsF-R1-01MD" check should be able to identify the presence of download web services, at least the most used ones such as the Open GeoSpatial Consortium (OGC), that in Europe are the preferred way to publish spatial data and the recommended way by the INSPIRE Directive, the Infrastructure for Spatial Information in the European Community.
Steps to reproduce
Simply perform a check using one of the DOIs provided above.
