SICo. P Special Briefing Federal Semantic Interoperability Community of Practice (SICo. P) August 9, 2007 (Updated August 13 and 23, 2007) For Mr. Michael Krieger Director Information Policy OSD, Do. D CIO 1
Overview n n n SICo. P provided a set of briefing slides for the August 9 th meeting (Sections 1 -4). SICo. P addressed the issues raised in the August 9 th briefing by supplementing the slides on August 13 th with notes (Section 5). SICo. P had an extensive email discussion which the SICo. P Co-chairs compiled and distilled in the Summary Points on August 23 rd (see next three slides). 2
Summary Points n n The leadership of the Do. D Co. I (Mike Todd) and SICo. P (Brand Niemann) worked together on the FEA/OMB DRM 2. 0 - The Do. D Co. I was featured as a best practice for information sharing in a Co. I and SICo. P led the DRM 2. 0 Implementation Through Testing and Iteration Work Group. The Do. D Co. I and SICo. P continue to interact in the Do. D Co. I Quarterly Meetings and through those with joint membership like Jim Schoening who leads the SICo. P Cross-Domain Semantic Interoperability WG (CDSI WG) that produced a white paper that was discussed in the press and gave rise to the August 9 th briefing for Mr. Krieger and his MITRE staff. 3
Summary Points n n Do. D is using semantic technologies and standards, and the recent Do. D Co. I Quarterly Meeting on July 31 st featured two presentations of that (David Hanz, SRI, and Mary Parmelle, MITRE). The SICo. P members participating in the August 9 th briefing came away with a range of impressions of the Do. D Co. I leadership from (1) Do. D and the IC are about 3 - 5 years behind where we are and we're pulling away fast, to (2) we need to take the time to understand their use case for semantic technology and focus our discussion on how semantic technology can be used to support their mission. All the SICo. P participants came away with the desire to work on how to "get Do. D leadership moving in the right direction" at the upcoming NCOIC Plenary and WG Meetings September 17 -21 st, and the Metatopia Conference, November 5 -7 th. 4
Summary Points n n The SICo. P and NCIOC SIF WG activities are about adding value to and reusing the Do. D and Do. D Co. I net-centric information sharing work, not about critcizing, disrupting, or replacing it - we are two communities trying to better understand each other and help one another to achieve a common purpose - semantic interoperability in information sharing. SICo. P would like to see the Do. D Co. I Leadership and MITRE staff review and comment on the individual SICo. P member presentations on August 9 th, and especially the white papers from GSA, and give SICo. P members the opportunity to present our work in the Do. D Co. I Quarterly meetings and/or invite the Do. D Co. I members to the SICo. P and SOA Co. P meetings. 5

3. D. SICo. P White Paper 3 n n The Data Reference Model (DRM) Version 2. 0 had three components, Data Description, Data Context and Data Sharing. It pushed details to Communities of Interest because they “knew best”. It encapsulates but does not solve all pre 2006 problems with data representation and sharing. In 2006 several Computer Science breakthroughs occurred which made DRM 2. 0 obsolete: DRM 3. 0 will have only two sections. 20
3. D. SICo. P White Paper 3 New Computer Science Breakthroughs n n n English was ambiguous and could not be made otherwise Verbs describing processes could not be described Schemas, XML etc. were near useless n n n English has been disambiguated and exact descriptions can now be created Formal descriptions of Verbs’ processes are possible and unique Schemas can be made usable 21
3. D. SICo. P White Paper 3 n Failure Points Can Be Addressed: ¡ ¡ COIs work can be made useful provided the exact semantics of their work products are specified exactly Schemas need to be accompanied by exact English descriptions of their meaning, but if so can be useful Knowledge Bases can now be built …. But: you cannot use 1960 -70 s methods to do this, nor just XML! You also need better contractor support, some A-team members. 22

3. E. Framework for Achieving and Managing Interoperability n Meeting the Interoperability Challenge: ¡ Critical success factor is to get ahead of the harmonization problem n n ¡ Essential Components for Interoperability: n n n ¡ ¡ Stop chasing and start managing the problem. Lack of direction and guidance at all levels of architecture leads to lack of interoperability. Core metadata (Do. D has achieved this). Metadata semantics and specifications for each attribute. Guiding Principles at the attribute level. Participation of stakeholders. Defined governance roles and processes for attributes. Metadata and semantics provide the framework that supports participation. Participation, guiding principles and governance models provide the synchronization and agility that is necessary for a complex, dynamic and multi-disciplinary organization. 25
3. E. Framework for Achieving and Managing Interoperability n Degrees of Interoperability: ¡ First degree -- core metadata set: n n n ¡ Identify the essential core set from what exists. Map and harmonize what exists. Implement new attributes. Design metadata architecture around core metadata. Define and publish specifications. Second degree – manage values: n n n Define guiding principles, policies and governance roles for core metadata. Establish change management process for core and institutional metadata. Establish and synchronize roles and responsibilities across the organization – these can be flexible but bounded. Involve business owners, domain experts, ontologists, taxonomists and metadata managers in appropriate roles. Whether you use a federated or centralized governance model is less important than the lack/availability of a governance model. 26
3. E. Framework for Achieving and Managing Interoperability n Degrees of Interoperability (continued): ¡ Third Degree -- converge application and service development: n n ¡ Development has a metadata component – review is at the attribute level. Ensure that all COIs and systems developers are building to the same framework. Anchor development around an enterprise level metadata dictionary. Involves continuous awareness raising and advocacy. Fourth degree – automate and monitor values: n n Configure semantic technologies to support metadata. Embed ‘vocabularies’ into technologies. Shift Co. I domain expertise to building and populating the semantic tools. Leverage semantic technologies to support consistent capture and population of the metadata values. 27
3. E. Framework for Achieving and Managing Interoperability n Lessons Learned and Best Practices: ¡ ¡ ¡ Develop guiding principles and governance processes for Do. D core metadata attributes. Broaden the ‘ownership’ of governance by implementing a governance process for each core attribute. Continue to leverage the Co. I’s but clarify their roles in the governance model. Implement a common and automated method of generating ‘metacards’ across the agency. Ensure that you have a well defined and efficient metadata architecture at the enterprise level. Implement semantic technologies (with embedded integrated values) at the core metadata attribute level at the ‘metacard’ level. 28
3. F. Semantic Wiki and New OS/NII Project n Architecture Federation Pilot: ¡ ¡ Army Chief Information Officer (CIO/G-6) Architecture Operations, Networks and Space (AONS) Directorate, Army Architecture Integration Center (AAIC) 29
3. F. Semantic Wiki and New OS/NII Project n Purpose: ¡ Portfolio management and investment planning activities: n The Do. D EAC COP had previously determined that a complex set of diverse information sources need to be tapped into and merged with the assets represented in architectures in order to supportfolio management. 30
3. F. Semantic Wiki and New OS/NII Project n Purpose (continued): ¡ Integrate knowledge in support of investment decision making by the following stakeholders: n n Joint Net-Centric Operations Capability Portfolio Manager (JNO CPM). Joint Focused Logistics CPM. Joint Command & Control (JC 2) CPM IT Portfolio Managers at both Do. D and Service levels. The Business Transformation Agency (BTA). 31
3. F. Semantic Wiki and New OS/NII Project n Classification Ontology: ¡ Engage a COI to build an ontology that is suitable for classifying the diverse collection of artifacts: n n n Common service capabilities and their related definitions. An architectural model of a sub-set of currently deployed Army tactical enterprise services, developed in DODAF constructs. An architectural model of a sub-set of Army tactical enterprise services as planned for future deployment. An architectural model of a sub-set of supporting Do. D IT infrastructure. An EXCEL spreadsheet containing a set of Army systems and related attributes. 32
3. F. Semantic Wiki and New OS/NII Project n Semantic Wiki: ¡ A semantic wiki will be used to develop the classification ontology: n n n A Community of Interest will be formed on the wiki. Stakeholders will collaborate over the definition of the ontology. The ontology will be published to a repository. 33
3. F. Semantic Wiki and New OS/NII Project n Repository: ¡ ¡ n The ontology will be imported into a commercial repository. All of the architectural/capability artifacts will be imported into the repository. Semantic Mapping: ¡ A semantic mapping tool will be used to match all of the artifacts to the semantically correct nodes in the ontology. 34
3. F. Semantic Wiki and New OS/NII Project n Result: ¡ Having all of the artifacts related to the ontology will facilitate the answering of the following kinds of questions: n See next two slides. 35
3. F. Semantic Wiki and New OS/NII Project n n n What are the capabilities and capability increments of interest? What are the representative echelons of the federation: nodes and ”edges”? For each echelon: ¡ ¡ n What are the minimum and desired capabilities, and when are these needed? What are the points of intersection/interfaces between echelons? Who are the providers (POR or otherwise) and consumers? What are the federation alternatives for each point of interface? For each provider: ¡ ¡ ¡ What increment of a given capability does it offer and what capacity does it have to serve consumers by FY? How much will this service cost to procure by FY? How much will this service cost to sustain by FY ? 36
3. F. Semantic Wiki and New OS/NII Project n n n What dependencies does this service have on other providers by FY? What is the ’interface’ (e. g. protocol) provided for federation with other providers to implement a given enterprise-wide capability? For each ‘interface’: ¡ ¡ What is that interface’s dependence on lower-level protocols? What are the Qo. S/transport/bandwidth dependencies? What are the rules for connecting to it? (e. g. information assurance (IA) credentials? ) What is the quality/accuracy/timeliness/consistency specification for that interface (e. g. : ”we will provide blue force locations that are no more than 5 minutes old within nearest 1000 meters. ”) 37
