For meeting with delegation from the Japan Construction Information Center, in response to questions provided ahead of time

1. NET-CENTRIC DATA STRATEGY JACIC visit 28 April 2009 Deborah L. MacPherson W3 Design Issues

2. Q: What is the means what users share raw data? Data sharing is realized by Viewing data through browser? Are users able to get data files and reuse? A: Depends on the type of data being used. Building geometry is different than relational databases, which are different than contract and specifications documents. All are behind biology and other fields.

3. Q: What kind of data type which user can get from the system, those are not only XML data but also non-XML data? A: XML is serialization only, ideal exchanges would involve: Industry Foundation Classes (IFC), ISO 16739 is version 2, v4 is being developed; International Framework for Dictionaries (IFD), ISO 12006 part 3, and a combination of UniFormat preferred by Owners, to MasterFormat used in construction documents, and OmniClass to be used over the building lifecycle Serialized XML Schema for Grid, by Syncfusion A Concept Can Exist Only Once! From IFD _in_a_Nutshell

4. Q: Is the type of spatial data which user can get from the system not only XML data but also “shape” or “klm” data? A: Interoperable shape data could be traced to the Standard Exchange of Product Data, STEP, ISO 10303 and Industrial Exchange ISO 15926. Interface with KML is led by the Open Geospatial Consortium.

5. Q: What is the name of system to be able to get data? Does the system federate to DoD MDR? A: Please contact Amanda Vizedom, Technical Lead Air Force Enterprise Vocabulary Team (EVT). Semantic SOA End State Request Response DBMS Web SAN … Core Data Exposure Services Existing Infrastructure Request Response Core Data Payloads Aggregation Services Request Response Request Response Aggregation Payloads Metadata Population MDE Metadata Catalog ADS Access Rules Ontologies Access Rules Ontologies COI Vocabulary Products – Managed in Metadata Registry inside MDE Federated Search Service Query Processing Service End Users

6. Q: Do you have any guidelines or rules for the restrictions relating to using data? A: Documentation is released in specific increments to comply with contract clauses. No documentation is public until such drawings and specifications are released, then authorized access is typically provided via an FTP. The construction site demands paper that cannot be changed. A current challenge is linking building data to jurisdictions, manufacturers, and others that only require certain parts of the information.

7. Q: How did operations of the business change before and after the introduction of the Net Centric data Strategy? A: Cloud computing will help large scale interoperability in the future, today operations and business rules are being developed ad hoc firm by firm, individual by individual, specialty area by specialty area. Ad-hoc Multihop by the University of Aachen Communication and Distributed Systems Department

8. Q: How did the introduction of Net Centric data Strategy effect the cost and burden of the job to reduce? A: NIST estimates waste alone consumes billions of dollars.

9. Q: Do you have any tools for supporting to change non-XML based data specification to XML based data specification ? A: Refer to this suite of Organization for the Advancement of Structured Information Standards (OASIS): EDXL, OBIX, ebXML, UBL, WS-Context, and XML Catalog v1.1 abstract

10. Q: How long does it take a time to design and investigation before developing the registry? How long does it take a time to start real operation after developing the registry? How long did you take a time for a trial before starting real operation of MDR? A: Depends on the project. The Open Floor Plan Display project with Golden Gate Safety Network, NIST Building Fire Research Lab and buildingSMART alliance would be an excellent case study. Common Operating Picture by Golden Gate Safety Network right.

11. Q: How many people are involved? What kind of organs judge the registering item? (Work Group? Committee? special post for judging? ) How often request to register? Do you have any guidelines for evaluation of registration? A: Typically a work group, sub work group, and community of interest model. NASA common operating picture at right.

12. Q: Do you have the function of not only showing a link to the place of data by metadata, but also getting XML data directly? A: Please see BIMstorm by Onuma Planning System, also the OGC Architect, Engineer, Contractor, Owner, Operator (AECOO) testbed where XML and IFC's are used in combination.

13. Q: If you can directly get XML data, registry has a function of transforming non-XML data to XML data? A: XML only serves one role, the drawings and actual data still need to be presented, and shapes and locations still need to be calculated, performance requirements are still in structured text. All are only Representations of reality and could be misread.

14. Q: Do you have any tool of transforming data between different data specifications? If you have any tools, how to do mapping data similarity between non-XML data and XML data also between XML data and another XML data? A: For buildings, the units and measurements continue to be important and some tolerances need to be maintained regardless of transformation. map map RDL ISO 15926 Company “ Acme” Company “ Emca” Reference Data Library Interoperate The iRING RDS/WIP

15. Q: When you develop Thesaurus, how do you evaluate similarity of semantics and relativity between each words. Is the way of evaluation by human or by tool? A: Takes both, for excellent example please refer to the Metadata Architectural Contents of Europe project (MACE) especially the Classification Browser .

16. Q: What is the movement of next stage of data sharing and discovery? A: Web services and more customizable controls - from better equipped conference rooms to smarter phones, sensors and measuring devices that let buildings report their own data, and the ability to converge multiple libraries, thesaurus, models and maps together depending on what you want to know or show.
