年度十大经典语句之首,我父亲看了后,也说了一句:有其师必有其徒啊!
因为不同班,跟李雪接触的机会就少了很多,我不太好意思去重点班找香港六合彩,顶多在放学后瞅准时间跟香港六合彩搭伴一起回家,以这样的速度,可想而知,与李雪的发展是多么缓慢.很多时间,我都产生了很强的自卑感,总觉得那个班都是玉树临风的才俊和闭月羞花的美女,渣子级别的都混到了初一(4)班里,我似乎被那些人渣给同化,心理上郁闷得厉害,除了英语和作文尚可外,其香港六合彩科目都让我兴趣索然.
第一学期结束,我凭着在小学时的深厚底子,没费什么劲儿就拿到了全年级第四,而我的梦中情人李雪不知道费了多大的劲考了个第三名.
显然,第一回合我输了,不是输给李雪,而是败给了重点班这个称号.
进入初中以后,有很多事都让我趋向成熟,最好奇的莫过于高年级男女同学的出双入对.
早恋的师兄师姐们有这样几个特点:上课传纸条的多(耳闻);课间挨在一起说甜言蜜语的多(鼻嗅);放学不立刻回家,操场上、角落里、教室中作依依不

    14. 14. Standards Activities <ul><li>ISO Metadata Update </li></ul><ul><li>OpenGIS specification status </li></ul><ul><li>Clearinghouse and OGC “Catalog Services” </li></ul>
    15. 15. ISO Metadata 19115 <ul><li>Still pending Draft International Standard </li></ul><ul><li>Schemas are being worked on as informative documents, still problems </li></ul><ul><li>Core metadata: http://130.11.52.184/datasetMetadataCore.doc </li></ul><ul><li>Diagram overview of Schema: http://130.11.52.184/19115overview.png </li></ul>
    16. 16. OpenGIS Consortium (OGC) Specs <ul><li>Web Mapping Service (WMS) 1.0 defines request, response, and query of data as maps </li></ul><ul><li>Geography Markup Language (GML) 2.0 is issued as an Implementation Specification, defining XML structures for vector Features used by Web Feature Service (WFS) </li></ul><ul><li>Gazetteer and Thesaurus have been issued as Discussion Papers </li></ul><ul><li>OGC website: http://www.opengis.org </li></ul>
    17. 17. OGC Catalog Services <ul><li>Catalog Services were made a specification in 1999 by the OGC to facilitate discovery of spatial data and services within a community </li></ul><ul><li>General model designed using the best features of Z39.50 </li></ul><ul><li>CORBA and WWW (Z39.50) Profiles demonstrated </li></ul>
    18. 18. Features of Catalog Services 1.0 <ul><li>A catalog can reference data or services </li></ul><ul><li>Multiple query languages supported </li></ul><ul><li>Common Query Language (CQL) is described as one language using BNF as a subset of the SQL WHERE statement against abstract target fields </li></ul><ul><li>Capabilities function intended to share service details (like explain) </li></ul><ul><li>Element set concept preserved (Brief, Full) </li></ul><ul><li>Response format preserved (XML, HTML, etc) </li></ul>
    19. 19. Consolidation for Version 2.0 <ul><li>“Stateless” (catalog over HTTP) proposal will be incorporated into OGC Catalog Services specification </li></ul><ul><li>Services will consider symmetry with Web Feature Services and Web Map Service </li></ul><ul><li>Revise/review CORBA and WWW (Z39.50) Profiles </li></ul><ul><li>Publish version 2.0 by September OGC meeting in DC </li></ul>
    20. 20. “ Stateless” Issues <ul><li>Would not require software to maintain a session between client and user </li></ul><ul><li>Would operate over port 80, reducing firewall issues </li></ul><ul><li>Operates as a web service, so if the web server is running, the search should work, too </li></ul><ul><li>Still requires a search engine or database and structured metadata </li></ul>
    21. 21. 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
    22. 22. 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
    23. 23. 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
    24. 24. Data and Service Catalogs <ul><li>ISO TC 211 Metadata Standard 19115(DIS) specifies data access handles and services metadata </li></ul><ul><li>Both service and data metadata should use linkages to exploit associations and minimize redundancy of information storage </li></ul><ul><li>EO/GEO approach provides a growing foundation of data descriptions that can point at formal service bindings </li></ul>
    25. 25. Service Catalogs <ul><li>Universal Description, Discovery, and Integration (UDDI) specification and Web Services Description Language (WSDL) defines a services description approach </li></ul><ul><li>OpenGIS Consortium is documenting the preferred strategy in Web Services Architecture (General Service Model, Basic Service Model) </li></ul>
    26. 26. OGC Network <ul><li>OGC-N Project this year will establish baseline infrastructure for discovering and testing OGC-compliant services </li></ul><ul><li>Desire establishment of reference implementation software clients and servers for community use in “compatibility testing” </li></ul><ul><li>Will include a discovery portal of OGC community data/services providers </li></ul><ul><li>Contact Jeff Harrison [email_address] for more info on sponsorship </li></ul>
    27. 27. FGDC Deployment <ul><li>12 sites will collaborate with FGDC in implementing catalog services for data and services to be deployed operationally within OGC Network </li></ul><ul><li>Services will include data catalogs, a common service registry, Web Mapping Services, and possibly Web Feature Services </li></ul><ul><li>Timeline: July 2001 – June 2002 </li></ul>
    28. 28. Other Business <ul><li>Should we schedule a 3-day NSDI Workshop later this year? Yes! </li></ul><ul><ul><li>Topics to cover: metadata, clearinghouse, web mapping, framework integration </li></ul></ul><ul><ul><li>Volunteers: need trainers, presenters, logistics support </li></ul></ul><ul><ul><li>Intended audience and participants: technical </li></ul></ul><ul><ul><li>Facilities requirements: multiple rooms with networked computers </li></ul></ul><ul><ul><li>Preferred locations: Denver or Phoenix </li></ul></ul><ul><ul><li>Preferred date: October 2001 </li></ul></ul><ul><li>Next telecon </li></ul><ul><ul><li>Date not scheduled.
