Who am I?

LOD Cloud 2014 Muninn WW1





Who am I?

CWRC





First ? ? ? ? ? data set on the Canada Open Data Portal





Presentation Outline

1 Who am I?

2 Why Linked (Open) Data?

3 Field notes on vocabularies

4 Field notes on publishing data

5 Field notes on working with triples





The business value of LOD.Citations! If you can cite it, it exists!Externalize your costs to someone else.Document your data’s idiosyncrasies.Linked Data is just another fad.It’s already on my website.People will steal my data.There are errors is my data.

Observations:1 There is a bigger market for the individual pieces of your

publication than the whole of it.2 There is a bigger market for your data with people that

don’t share your alphabet.Warren et al Operationalizing Linked Open Data,. . . 6/31




The propeller-head value of LOD.You have a machine readable URI to work with.You can support multiple serializations.You can still reference something, even if not “Open”.You can annotate the data to the nth degree.Easy provenance and tracking of changes.You get multiple languages and Unicode for free.

Observations:1 Forces separation between the data and the application.2 Your use cases for the data are never what people want

out of the application.3 LOD engages with people by engaging their machines.





Vocabularies: Use a standard. (Which one!?)

a

ahttps://xkcd.com/927/


https://xkcd.com/927/




Vocabulary use options:1 Create your own.2 Use one existing vocabulary.3 Use multiple existing vocabularies.

The data consumer’s perspective:Consumers want to know what to expect in vocabularies.Multiple vocabularies need relationships. (You build them).The vast majority of data consumers cannot useontology reasoning at query time.





Case Studies:

Overview: CWRC (http://www.cwrc.ca/)Primarily Orlando TEI-style data.Schema definitions not ontologically sound.Custom ontology linked to other ontologies.Questions of ethnicity, race, skin colour alternate betweenvernacular and technical.


http://www.cwrc.ca/




Case Studies: CWRC Entry

a

aAnna LeonOwens





OutcomesThe Ontology is a data explanation tool. Initially (wrongly)seen as a controlled vocabulary.Much time is being spent on teasing out the intent of thedata as written.The process is very demanding of the scholars.The CWRC ontology in its final form will have paradoxes.Acceptable because it explains data that was not builtwithin an ontologically rational framework.This is good enough for partial data exchange.Massive ancillary linkages to other dataset.





Case Studies:

Overview: Muninn (http://rdf.muninn-project.org/)Heterogeneous data sources: text, SQL, images, free formtabular.Erroneous, ambiguous and incomplete data.Multiple purpose built ontologies for specializedapplications.Move to standardized ontologies as they become available.(re: Organization Ontology)No “single” truth, but you are free to decide for yourself.

Field notes on Vocabularies: Conclusions1 The public interacts with Applications not Data, but

Data is why we are here.2 Do not ever design vocabulary for the application.3 Old data is never clean, sensical or well behaved. The

ontology / vocabulary has to say so and work with it.4 Reuse vocabularies and create new ones on a case by

case basis.5 Great resource athttps://lov.okfn.org/dataset/lov


https://lov.okfn.org/dataset/lov




Publishing Linked Data:

Checklist:Dereferencable (URI’s for everything)?Content negotiation (The data format is dead.)?Public facing SPARQL server?Machine and Human readable vocabulary definition?Machine and Human readable data set definition?Production, in-house use of the SPARQL on day 1?





Important Note: People write bad programs.“If builders built buildings the way programmers makeprograms, the first woodpecker to come along would destroycivilization.” - Gerald Weinberg

Corollary:Get someone who knows public facing infrastructure to lookthings over for you.





SPARQL servers

SPARQL allows for custom retrieval queries over HTTP withouthaving you involved.





An important note about SPARQLRun SPARQL queries through a reverse HTTP proxy: ngix,polipo, etc.

Why?Offending programmers can be safely ignored.Allows for light infrastructure abuse (auto-completequeries).Improves performance without heavy planning.





Tracking data in large data stores:Generate more data as a byproduct of operations:It is easier to delete old triples than to rebuild triples thatshould have existed.Tracking provenance of node is trivial; consider building itinto your work flow.Data and meta-data are merging.The most awesome use of your data is a use case youhave not thought of.

Recap:Linked Open Data is about data, not applications.The thing and the name of the thing are not the same thing.The most awesome use of your data is a use case youhave not thought of.Vocabulary use means something.LOD engages with people by engaging their machines.
