A Tale of Two Elm Streets

Which ‘Elm St’ was that?

Betamax vs. VHS

WHAT HAPPENED, DUDE?

PIZZA bad or no results = ambiguous query

MEGA FORCE got results, not what was expected

BETAMAX results weren’t useful

WHAT HAPPENED, DUDE?

It’s A Hard Knock Life

Livin’ on a Prayer➢ “Grand Challenges” require data

➢ Right data has been hard to find

AHA #1: Data needs CONTEXT

http://www.oocities.org/sunsetstrip/4426/visual/faces.gif

What is it:

2 faces

- or -

1 candlestick

CONTEXTinfluences the understanding of a subject

by adding surrounding information.

Geospatial CONTEXT

VISUALIZING the CONTENT

VISUALIZING the CONTENT,

“STILL HAVEN’T FOUND WHAT I’M LOOKING FOR…”

Addressing the “Grand Challenges” requires interoperable systems

to aid in the discovery &

exchange of information.

AHA #2: Cooperative Data

Somewhere out there… where dreams come true.

Express Yourself

What does it mean to be “friends”?

What does “connected” mean?

➢ Family are “friends”➢ Co-workers are “friends”➢ High-school acquaintances are “friends”

Example: Walking on the Moon

http://astrobob.areavoices.com/files/2011/08/Moon-May-3-AS-Del1-1024x776.jpg

Copernicus plotted

http://stko.geog.ucsb.edu/location_linked_data

Is that the moon?

“One small step for man...” in South Sudan

APOLLO 11

http://dbpedia.oobian.com/#/OobianMaps/VPIN/dbp%253aCopernicus_(lunar_crater)

http://www.leftcoastgrassfed.com/

Example: Grass-fed beef supplier

SEARCH: “COASTAL BEEF”

http://www.leftcoastgrassfed.com/

IS “COASTAL BEEF” DEADLY?

AHA #3: Reliable data exchange needs semantic interoperability

➢ Sender knows Ready To Die is a “MusicalWork”

AHA #3: Reliable data exchange needs semantic interoperability

➢ Sender knows Ready To Die is a “MusicalWork”

➢ Receiver should interpret Ready To Die as a “MusicalWork”

Semantic interoperability

means shared UNDERSTANDING

throughout content exchange.

If your content is worthy of a website,then it deserves to be understood.

SCREENCAST

LINKED DATA in ACTION

https://www.youtube.com/watch?v=_bn4muKqXv0

MapServer

OpenSearch

Linked Data

Drupal

What’s the Stack, Yo?

http://mapserver.org/http://www.opensearch.org/http://www.w3.org/standards/semanticweb/datahttps://drupal.org/

LINKED DATA

http://www.ibiblio.org/hhalpin/homepage/presentations/tpac2008/rdf.png

What’s the big deal?

➢ Some facets are built from 3rd party

❏ Instruments by Type❏ Parameters by Type

Linked Data: The Deal

➢ repository of oceanographic terms

➢ vetted by oceanographers(pan-European project)

➢ exposed as Linked Data by BODC

SeaDataNet @ BODC

http://vocab.nerc.ac.uk/http://www.seadatanet.org/extension/seadatanet2/design/skin-seadatanet2/images/Logo_SeaDataNet_fond_transparent.png

One consumer was across the ‘pond’ - 3,000 miles away

It was assumed that SeaDataNet terms would be useful to others

1. Context through RDF vocabularies

2. Cooperation via common framework (RDF)

3. Cooperation without coordination

4. Semantic Interoperability through HTTP URIs for naming things

LINKED DATA + DRUPAL

http://www.ibiblio.org/hhalpin/homepage/presentations/tpac2008/rdf.pnghttp://fc03.deviantart.net/fs71/i/2011/179/c/d/vector_tree_by_axelintu-d3kedq3.pnghttp://drupal.org/files/druplicon.small_.png

RDF (core)➢ Entities have globally unique URIs

➢ Content Types = RDF Vocabulary Classes

➢ Fields = RDF Vocabulary Class Properties

http://calexis.com/blog/wp-content/uploads/2010/06/My-Name-Is.jpg

CONTEXT

RDFx (contrib)➢ Serializes content in RDF data model

(“structured data”)

○ 1 model = many formats■ HTML■ JSON■ XML■ TEXT

○ RestWSsupport

Vocabularies @ BCO-DMO

Ocean Data Ontology cruises, ships, instrumentation, measurements, funding

Dublin Core generic metadata

DCAT dataset catalog

FOAF people & organizations

VoID linking data

GeoSPARQL geospatial features

PROV-O provenance (revisions & activity)

QUERYING LINKED DATA

http://www.cedar-project.nl/wp-content/uploads/alibobo_w3cSPARQL-logo.png

OpenSearch

Linked Data

rdf_indexer (contrib)➢ Index data in triple store

➢ Uses Search API

➢ SPARQL endpoint

rdf_indexer (contrib)➢ Uses Search API

rdf_indexer (contrib)➢ SPARQL endpoint

rdf_indexer (contrib)

➢ Extensible for support of external RDF stores

○ BCO-DMO uses Virtuoso RDF store

○ submitted Virtuoso extension as a patch (https://drupal.org/node/2029717)

■ BCO-DMO SPARQL endpoint:

http://lod.bco-dmo.org/sparql

Enable rdf_indexer to make your data queryable.

New York Times: Innovation Report

“...there are substantial costs to waiting.”

RECIPES aren’t properly tagged

by ingredients and cooking time

“We can do it now,

but only after spending a huge sum

to retroactively structure the data.”

“The lack of structured data helps explain why we are...“

1. unable to automate the sale of our photos

2. continually struggle to attain higher rankings on search engines.

“We need to reclaim our industry-leading position,

but right now our needs are far more basic.

We must expand the structured data we create.”

“I like a good story, well told.” -Mark Twain
