Vocabulary Hub Changes to Business Layer

Adding new arrows for Vocabulary Provider

[VladimirAlexiev]

@ssteinbuss , @clange

• the edge "receive data" has no arrowhead
• more importantly: Data Consumer receives two crucial flows: Data and Vocabularies.
  • Is it not in scope for the Vocabulary Hub to provide mapping/semantization services that apply Vocabularies to Data and thus harmonize and semantize the data? Or the Consumer is left on his own to do tackle the difficult Data Integration problem?
  • Or in domains that already use semantic data, just bind ontologies to data (i.e. declare the meaning of data). Eg domains:
  • Electrical CIM/CGMES;
  • OntoCommons ontologies (in particular for Materials and Manufacturing data)

@ssteinbuss thanks a lot for the clarifications! Here's what I captured from our discussion, please correct me if I got something wrong:

• Look in the Process layer: #208: vocabulary service in the process layer
• Plenty of these "Semantization" aspects are already covered
• in particular, how Data Providers can make Data Offerings that include Self-Describing data
• But there's no mechanism yet for Data Providers to collaborate to ensure that their Data Offerings are harmonized. This is an aspect of Data Space governance, eg to mandate they use CSVW for describing CSVs, particular ontologies, SHACL shapes, etc
• Can data spaces use Linked Data principles as alternative to Connectors (transferring data inbulk)? LD principles are not in RAM 4.0, but can be in the Whitepaper, and make it into RAM 5.0
