Transcript of Interoperable Open Data, which Recipes?

Recipe for:
Sharing Open Data, e.g., allow 3rd parties
to build apps to search/browse/analyse/etc data about artworks
From the kitchen of:
Directions:
Data Publisher
Database or internal data --> Files (CSV, XML, SQL) --> CKAN, or even plain Web Server/CMS --> Count the downloads...
Recipe for:
Consume Open Data, e.g., build/use apps to search/browse/analyse/etc data about artworks
From the kitchen of:
Directions:
Data Consumer
Google (+ *.data.gov.*) --> Files --> Have a look (+ cry/scream) --> Pick decent ones --> clean-up (+ cry/scream again) --> convert to your own model/format --> build your app
A different recipe:
Database
standard formats
universal IDs
standard vocabularies/ontologies
Adopt:
Publish:
Files
(CSV, XML)
Original Files
LODs
Metadata
(DCAT)
Consume:
Data Access Standards
(resolvable URIs, SPARQL)
APIs
Data Access/Analytics Apps
(e.g., mash-ups, charts, searching/browsing)
Cleaners, Converters
Cleaners, Converters
Schema mappers
Concept mappers
Data integration, cross ref, etc
Schema/ontology resources
Documentation resources
Practices sharing
Tools
People
(e.g., guidelines, examples, use cases, wikis)
Web/Documentation

...
Free text, no identifiers
No Related entities details
Dirty data
Internal-only IDs
Custom syntax,
torturing unsuitable syntax
Structured content
into text
Is it about persons?
Do you like FOAF?
So, do you confirm/change foaf:givenName, foaf:surname, foaf:birthday, etc?
Map to IDs/resources
Map to vocabulary/ontology
dbr:Le_bonheur_de_vivre
dbr:Morphological_Echo
dbr:The_Ghost_of_Vermeer_of...

Examples
Data Set 1:
Simple CSV File
Data Set 2:
Semi-structured linked CSVs
Highly Structured XMLs
Ideal: RDF/LOD
Cleaners, Converters

Or maybe yet another approach?
Evangelization
on line (blogs, wikis, etc)
off line (OD/LOD dojos, hackathons, etc)
Pilot projects (ideally, through grants or alike, don't fit well with poor volunteerism)
Start from scratch, not from published data sets
eg, data entry tools
with pre-defined spreadsheets/forms
with stuff like auto-completion of vocabularies/codes/IDs (for instance, see OntoMaton, https://goo.gl/lkXC8L)
auto-derived from schemas/ontologies (eg, ShEx, https://goo.gl/Jlqnft)
