4E/ Semantic Interoperability with Layered Schemas and Semantic pipelines

From IIW

Semantic Interoperability with Layered Schemas and Semantic Pipelines

Tuesday 4E

Convener: Burak Serdar


Tags for the session - technology discussed/ideas considered:

Semantic interoperability, semantic harmonization, JSON-LD

Discussion notes, key understandings, outstanding questions, observations, and, if appropriate to this discussion: action items, next steps

Topics discussed:

  • Layered schemas as a tool for semantic harmonization of data

  • How to deal with variations of data coming from different sources

    • Example: One source represents date as unix timestamp, another uses yyyy/mm/dd, how to harmonize such data using layered schemas

    • Terms with functionality: examples on optionally validating data

  • The key idea is to capture raw data with metadata and to interpret it layer based on context

  • Semantic pipelines: ingest data, reshape data

  • Semantic pipelines as a web service

  • Problems with JSON-LD

    • JSON-LD is not namespace for JSON

    • JSON-LD cannot capture mappings of terms that mean one thing in one terminology but that means multiple things in another

    • JSON-LD is difficult to maintain because the meaning can be unrelated what can be inferred from the text
