UNEDITED NOTES

facilitator: Rob Sanderson

Things to Things

Dynamic

• provenance
• annotations as nanopub

Degrees of sameness

Outside our domain?

• no need to be perfect

Event stream

Use case – authorities

Deleted resources – tombstones

Entities joining/splitting

Alternate identities

Services/tools

• certainty and risk aversion
• more data = better, = more uses

(new group)

Sameness?

Reconcile at work level

Context – what we use the data for!

Reconcile most discriminant attributes

Similarity pocky  for sameness

• certainty?
• risk aversion
• discovery vs. inference/data management
• schema:samas – avoiding the alt itoces 

Indexing & uncertainty

• perfect as enemy of good enough
• sameAs external link as vote for URI
• distinctness different for different types of entity

special cases are special: Bible, Mark Twain

(new group)

Services like ref. cleaning

• identify auth. we trust
  • e.g., VIAF
• map between authorities
  • devil in details for mapping
  • mechanism to address errors in auth!
  • disambiguate

"Authority" – what do we really mean?

• Wikipedia/media wiki as authority
• Open URI resolver?
• endorsement of approach by adopters
• divide and conquer easy bits
• start with under-served domains
• cheaper going forward
• market will decide on URIs to use
• vocab/facet reconciliation
• places & dates, concepts with multilingual

(new group)

Ontology alignment

Global auth & global contexts

Dynamic entities : join/split

Pseudonym – Europe vs. US

Local assertion = local URI

Pre-existing identifiers

Link all the things

Subjects broader issue than people

• sameness degree?
• certainty?

Tools to produce the data?

• languages and character sets
• different to strings to things
• service to publish alignments
• provenance important for trust
