Implementing the Open Government Directive
using the technologies of theSocial Data Web
George Thomas, December 2009
2
This Presentation
• Demonstrates the value and utility of the Social Data Web
– Using two different Websites (part 1)
• One to host a few simple ontologies (metadata specifications)
– Using Semantic Web and XML standards based technologies
• And another to host their corresponding (instance) datasets
– With a Semantic MediaWiki (part 2)
• That imports both the ontologies and datasets off those 2 Web sites
– For easy human interaction - creation, curation and augmentation
• But maintains the independence of each domain ontology/dataset
– Making machine readable representations available on demand
• And proposes a HHS Open Government Directive project
– Realizing next-gen Performance Management
• By linking Mission Goals (why) with IT Investments (what) data
4
Metadata Specs Published on the Web
• 3 domain specific ontologies– /vcso/omg/bmm
• The OMG Business Motivation Metamodel (BMM)
– /fedsheets/omb/ex300 and ex53 • OMB Federal Capital Planning and Investment Control (CPIC)
• 1 integration or ‘bridge’ ontology– /bizmo (that connects CPIC and BMM)
5
• These datasets are instances of– http://ontologies.socialdataweb.org domain specific and
integration ontologies
• Simulating 3 different agency.gov/open data sources– Each builds on, and adds to the others, without changing them
Instance Data Published on the Web
6
it.usaspending.gov -> HHS Ex300
• Selecting columns to populate CSV
7
Spreadsheet->Ontology Pattern
• Get (raw?) data
– From http://it.usaspending.gov CSV download
• Worksheet name = Class name
– For example, an ex53 or ex300 spreadsheet
• ColumnName = Class Datatype Property
• Row = instance of Class
– First column (often) treated as record (row) PK
• Cells = instances of Datatype Properties
8
/fedsheets/omb/ex300/ex300.owl#
• Version 1.1 (shown here)
– 1 Class
– 25 Datatype Properties
• With XSD typed literal values
– Replaced xsd:string where obvious
• With xsd:float, xsd:int, and xsd:date
• Version 1.2 (future)
– Should refactor further
• Introduce more (obvious) types
• Reuse authoritative/defacto vocabs (!)
– And create more object props
• That link types to other types
9
OMB Ex300 Metadata Specs on the Web
11
/fedsheets/omb/ex53/ex53.owl#
• Version 1.1 (shown here)
– 1 Class
– 17 Datatype Properties
• With XSD typed literal values
– Replaced xsd:string where obvious
• With xsd:float
• Version 1.2 (future)
– Should refactor further
• Introduce more (obvious) types
• Reuse authoritative/defacto vocabs (!)
– And create more object props
• That link types to other types
12
OMG BMM Simplification
• Object Management Group (OMG) Business Motivation Metamodel (BMM)
– A desired result is a generalization of goals and objectives • A goal is something an Org is trying to
achieve• An objective quantifies a goal, specifying
timing and measurement– A course of action is something an Org
does to achieve a desired result• A strategy is a broad, lasting course of
action• A tactic is a narrow, fleeting course of
action– An influencer is something that can
affect the Org’s ability to achieve its goals or implement its strategies• An actuator is an influencer that can be
considered as a quantity that can increase or decrease over time
– An assessment is a judgment of an influencer’s affect on an Org

Full BMM Ontology in TBC-FE
• 51 Object Properties
<owl:ObjectProperty rdf:ID="focusesEffortOn">
<rdfs:domain rdf:resource="#Strategy"/>
<rdfs:range rdf:resource="#Goal"/>
</owl:ObjectProperty>
• 35 Classes
<owl:Class rdf:ID="Strategy">
<rdfs:subClassOf rdf:resource="#CourseOfAction"/>
</owl:Class>
<owl:Class rdf:ID="Goal">
<rdfs:subClassOf rdf:resource="#DesiredResult"/>
</owl:Class>

OMG BMM MetaModel (=Ontology)

BMM Legend: Means to End, Assets
• A ‘business view’ of the Business Motivation Metamodel (BMM)
• Let’s look at some BMM instance models and resulting data now!

CCAC BMM Ends: Instance Model

Bizmo ‘Bridge’ Ontology in TBC-FE

Key /bizmo.owl#Classes
26
Key Interlinking /bizmo.owl#properties
– #supports properties link CPIC ex53/ex300’s• to BMM Strategies, Tactics, Goals, Objectives, etc.
– extending the Ex53/300 specs – without changing them!
– #maintainsExhibit53/300 link OrganizationalUnit’s• to CPIC investment information

End of Part 1
• Recap:– We created and published 2 CPIC ontologies
• We created and published HHS instance datasets of each– Using data sourced from it.usaspending.gov, the ‘ITDB’
– We created and published 1 BMM ontology• We created and published CCAC, AIC and HHS instance datasets of
the BMM– Mostly on the subject of Cloud Computing
– We created and published a ‘Bizmo’ bridge ontology• We created and published Bizmo instance datasets that link HHS CPIC
(what) datasets to a variety of CCAC and AIC BMM (why) datasets
• What now?– Let’s interact with all this!
• Using the ubiquitous, free, open source and arguably the most successful social networking tool ever!– MediaWiki, the software that powers Wikipedia.org
31
Browsing SMW KB via Classes
32
Browsing SMW KB via Properties
33
Ontology Classes/Properties = Tags
• Create semantic annotations (part of wysiwyg editor tools)– auto-completion suggests tags to reuse from ontologies that have
been imported into the wiki (note existing tags from BMM ontology)
34
Ontology based SMW KB Query

SMW KB Report Generation

Exhibit300 ‘Facts’ about HHS UFMS

NHIN – Automagic Data Merging
38
NHIN RDF/XML IEP: Export Excerpt
• Wiki instance data and metadata curation (SME edits) maintain class and property specs of ontologies imported off the Web when exported or accessed by other sites/users/apps
39
Browsing Linked Datasets on SMW
• Filtering through properties defined by Bizmo ontology• finds CPIC instance data that is linked to BMM instance data
40
SDW = SNS enabled LOD• This presentation is summarized by the interactive data below• And - it’s a Wiki – SME’s can easily add annotations and data!
End of Part 2
• Recap:– We imported the ontologies and datasets on the Data
Web (from Part 1) into a Semantic MediaWiki (SMW)– We interacted using ‘Halo’ SMW tools by;
• Browsing the instance data via ontology classes and properties (aka ‘faceted browsing’)
• Curation of imported instance data and adding semantic annotations, creating new metadata and instance data
• Querying the wiki using ontology classes and properties and instance data Web ID’s (aka URI’s)
• Navigating from ‘facts’ about any datum to any other• Extracting data from the Wiki in a variety of machine and
human readable output formats
Conclusion
• This presentation has demonstrated an implementation of;– Social Data Web features and functionality– That links Business Strategy with IT Investment data– Using existing free and open source software tools– To design ontologies (metadata schemas) that enable– Federated instance datasets to be integrated– Treating both metadata & datasets as social media– All of which are implemented on the Data Web– Without writing one line of application code
Proposal
• Continue this SDW work– Under the auspices of the HHS Innovation Council
• And continuing with the W3C eGov IG
– Targeting Federal CIO Council and OMB Ends• Stand up SDW as stated in AIC Cloud Computing proposal• Demonstrate next-gen IT Dashboard functionality
– As part of HHS OGD response plan
• Next steps– Add OMG FEA and MPG metamodels and defacto vocabularies
(DC, FOAF, SIOC, etc.) and DSL’s (risk, security, etc.)• Refactor example ontologies accordingly
– Stand up GovGOALS using SMW+Halo on public cloud (move off my laptop )
• Create/demonstrate syndication/dissemination capabilities
