Building arguments on open data

Intro

What? 

• Explore data portal/catalogs

• Chunk up data and reassemble into a meaningful argument

• Share that argument

• Have others derive work from your findings

Intro

Ultimately...

• goal is to model and share a thought process based on open data

Intro

• has to be 
  • shareable -> open data
  • verifiable -> assessment of authenticity of sources
  • reproducible -> standards-based, open description of process

Preamble : Data standards

Tech

as the 3rd star of open data, it should be obvious by now...

• XLS sheets
• ZIP files
• a link to a webpage that gathers some data
• ....

Verifiability & reproduceability
--> capture data lineage

Tech

Towards a Mosaic standard : Metadata standards

• data provenance metadata
  • origin
  • authenticity
  • ​based on Dublin Core vocabulary
• data processing modelling
  • need for data process description vocabulary
  • Considered ontologies: OntoDM, DMOP

qualifying annotations

--> per domain controlled vocabularies

Tech

Towards a Mosaic standard : Controlled Vocabularies

• largely based on         Open Annotation Model

Tech

Towards a Mosaic standard : Annotation Model

• consolidates URL fragment syntax

• standard modelling language for visualization

Grounding Data

Annotations model is RDF-based and queriable in SPARQL

--> graph of all annotations constitutes grounding material
      for data itself, and gives context and semantics to data
