时高声喝喊的萧方,提着香港六

合彩那把超大号的片刀,先是冲着萧方的方向一路小跑,等香港

六合彩认为已到了自己的攻击范围之后,一声断喝,速度瞬间提

升,快似闪电,向萧方飞驰而来。萧方左右有不下十名南洪门的

精锐做为香港六合彩的护卫,见状,纷纷抽刀挡在香港六合彩身

前,迎击冲来的吴常。香港六合彩没到,刀已经高高的举起,等

吴常到了护卫近前,不管对方是谁,抡臂就是一刀。刀身本就沉

重,加上香港六合彩身体向前的冲力和臂膀挥舞的力量,刀身划

过空气时竟然发出了狂风呼啸的声音。

南洪门护卫见香港六合彩锐不可挡,不敢大意,又不好侧身闪躲

,最前方的三个香港六合彩几乎同时横起刀,硬接香港六合彩来

势汹汹的一击。

刀刀结实,先是一声刺香港六合彩耳鼓的尖锐响声,接着传来三

声惊叫,等萧方和南洪门香港六合彩看清楚之后,无不在心里颤

原来吴常一刀砍出,硬声声把三位横刀招架、膀大腰圆的大汉凌

  • CAP Grants information
    • FY 2001 CAP Coop Agreements are being issued
    • “ Don’t Duck Metadata”, US-Canada Framework, Metadata Trainer, Partnership, and Web Mapping award categories
    • Period of performance, starts soon, lasts for 12 months.
  • Standards Activities
    • ISO Metadata Update
    • OpenGIS specification status
    • Clearinghouse and OGC “Catalog Services”
  • ISO Metadata 19115
    • Still pending Draft International Standard
    • Schemas are being worked on as informative documents, still problems
    • Core metadata: http://130.11.52.184/datasetMetadataCore.doc
    • Diagram overview of Schema: http://130.11.52.184/19115overview.png
  • OpenGIS Consortium (OGC) Specs
    • Web Mapping Service (WMS) 1.0 defines request, response, and query of data as maps
    • Geography Markup Language (GML) 2.0 is issued as an Implementation Specification, defining XML structures for vector Features used by Web Feature Service (WFS)
    • Gazetteer and Thesaurus have been issued as Discussion Papers
    • OGC website: http://www.opengis.org
  • OGC Catalog Services
    • Catalog Services were made a specification in 1999 by the OGC to facilitate discovery of spatial data and services within a community
    • General model designed using the best features of Z39.50
    • CORBA and WWW (Z39.50) Profiles demonstrated
  • Features of Catalog Services 1.0
    • A catalog can reference data or services
    • Multiple query languages supported
    • Common Query Language (CQL) is described as one language using BNF as a subset of the SQL WHERE statement against abstract target fields
    • Capabilities function intended to share service details (like explain)
    • Element set concept preserved (Brief, Full)
    • Response format preserved (XML, HTML, etc)
  • Consolidation for Version 2.0
    • “Stateless” (catalog over HTTP) proposal will be incorporated into OGC Catalog Services specification
    • Services will consider symmetry with Web Feature Services and Web Map Service
    • Revise/review CORBA and WWW (Z39.50) Profiles
    • Publish version 2.0 by September OGC meeting in DC
  • “ Stateless” Issues
    • Would not require software to maintain a session between client and user
    • Would operate over port 80, reducing firewall issues
    • Operates as a web service, so if the web server is running, the search should work, too
    • Still requires a search engine or database and structured metadata
  • native client protocol server catalog A P I Current Catalogs Z39.50 or CORBA protocol This model applies for both the current Z39.50 and CORBA implementations Send query Get response Return metadata Request metadata
  • Web client other client Web Server Web CGI catalog A P I Send query parser (mp) Return metadata Stateless Catalogs HTTP POST Z39.50 Service would be replaced by similar functionality hosted as a Web Service over port 80
  • Stateless Catalogs Web client XML client Web Server SOAP listener catalog A P I Send XML XSLT Return Full XML SOAP is a platform-independent style of CGI handler that dispatches programs to compile a response. Isite will be renovated to include a SOAP interface for local http-based query to replace Isearch.cgi HTTP POST
  • Data and Service Catalogs
    • ISO TC 211 Metadata Standard 19115(DIS) specifies data access handles and services metadata
    • Both service and data metadata should use linkages to exploit associations and minimize redundancy of information storage
    • EO/GEO approach provides a growing foundation of data descriptions that can point at formal service bindings
  • Service Catalogs
    • Universal Description, Discovery, and Integration (UDDI) specification and Web Services Description Language (WSDL) defines a services description approach
    • OpenGIS Consortium is documenting the preferred strategy in Web Services Architecture (General Service Model, Basic Service Model)
  • OGC Network
    • OGC-N Project this year will establish baseline infrastructure for discovering and testing OGC-compliant services
    • Desire establishment of reference implementation software clients and servers for community use in “compatibility testing”
    • Will include a discovery portal of OGC community data/services providers
    • Contact Jeff Harrison [email_address] for more info on sponsorship
  • FGDC Deployment
    • 12 sites will collaborate with FGDC in implementing catalog services for data and services to be deployed operationally within OGC Network
    • Services will include data catalogs, a common service registry, Web Mapping Services, and possibly Web Feature Services
    • Timeline: July 2001 – June 2002
  • Other Business
    • Should we schedule a 3-day NSDI Workshop later this year? Yes!
      • Topics to cover: metadata, clearinghouse, web mapping, framework integration
