Lessons learnt from DCAT-AP.de
+ ADMS, DCAT and LOCN cover most German requirements
+ joinup was very useful for public participation process creating > 200 commentsreceived
+ reuse of dcat-ap saved a lot of work and was a huge plus in acceptance management
- ISA² Core Location “locn:address“ did not fit for various reasons
- Ambiguous terms in adms:publisherType and adms:licenseType
- role model, locn:address and licenseAttributionByText require a dcat revision
- rdf validation of dcat-ap.de datasets is a challenge (SHACL?)
Tracking (some) changes to dcat-ap
license distribution restricted made license a mandatory field out of a set of licenses
dcatde:contributorID dataset added
added an ID property out of a given set of IDs for contributing data portals as a
mandatory field
dcatde:legalbasisText dataset added
added a field to contain reference to PSI and other legal sources that led to the giving
access to this document / dataset
dct:contributor dataset added enhanced role model
dct:creator dataset added enhanced role model
dcatde:originator dataset added
Enhanced role model, for temporary use only while waiting for a solution in dcat-ap or
dcat.
dcatde:maintainer dataset added
Enhanced role model, for temporary use only while waiting for a solution in dcat-ap or
dcat.
dcatde:politicalGeocodingURI dataset added
added properties to contain information in redundant addition to dct:spatial in a more
structured way
dcatde:politicalGeocodingLevelURI dataset added
added properties to contain information in redundant addition to dct:spatial in a more
structured way
dcatde:geocodingText dataset added
added properties to contain information in redundant addition to dct:spatial in a more
structured way
description distribution less restricted changed bindingness from "recommendation" to "optional"
modified distribution recommended changed bindingness from "optional" to "recommended"
catalog record excluded in general supported but not used by examples or reference implementations
spdx:hashAlgorit
hms added added own namespaces to contain references to additional hash algorithms
