Architectures as Data

Architectures are critical government data assets

Business models, process models, service models, information models,
rules, metadata, ontologies, technology models, schema
 There is an enormous asset in this existing architectural data





Architectures describe government, how it works, its resources and
services
Architectures make other data more valuable – describing data or
how it was produced
The most valuable architectures are models with a formal meta
model or schema
Currently – most models are not web data accessible, they are
trapped in tools and files. Models are not linkable.
Viewed another way, architecture models are just data – data to
be federated, analyzed, queried, linked and mashed up – data to be
published as LOD

Architectures Models Are Trapped
in Stovepipes
Architecture Models hold our enterprise Architectures,
business processes and services, technology models,
SOA architectures, data schema and more
But, model files are not web assets and hard to connect
Information is unconnected, redundant and not usable outside its source

Architectures Published into the
Data Cloud
Visible architectures have more value!

High level plan
1.
2.
3.
4.
Publish architecture models as LOD, in their original
vocabulary
Develop well defined semantic hub models,
vocabularies of “shared concepts”, and map the raw
architecture data to these hubs
Develop various tools and techniques for querying,
viewing, federating and analyzing the data for various
stakeholders to enable visibility and collaboration
Provide for external comment and input for participation
– federated architectures become read/write

Architecture Model Standards

Object Management Group (OMG) has adopted many of the
architecture modeling standards








XML Model Interchange (XMI) – Data Interchange for models (E.G.
Eclipse EMF)
Unified Modeling Language (UML)
Business Process Modeling Notation (BPMN)
Service Oriented Modeling Language (SoaML)
Etc…
There is an enormous asset in these modeling concepts
All OMG and many other model tools interchange via XMI
Goal 1 – Publish any/all XMI based models as web Linked Open
Data

All UML, BPMN, SoaML models become linked open data assets

Structurally Mapping XMI and RDF

What is does






There is a very direct structural mapping between the XMI and RDF
representation of a model
This mapping is isomorphic (no information loss in either direction)
Any XMI model (UML, BPMN, Etc) can be automatically and isomorphic
mapped to RDF as Open Linked Data
Models become part of the open linked data cloud
Everything is mapped, not a subset
What it doesn’t do

The vocabulary and meta model of the source is retained, this publishes
the model data as LOD, it does not do a semantic mapping
 Semantic mapping is a separate step
