18. 26 September 2002 Archibald Warnock (warnock@awcubed.com) FGDC Support Activities Archie Warnock, A/WWW Isite Updates CIP/GEO Interoperability Testing ISO 19115 CD2 Metadata Support Activities

19. Isite Updates ftp://ftp.awcubed.com/pub/Software/Isite2 GEO Compatibility Fixed date range syntax (CCYYMMDD/CCYYMMDD) Uses structure attribute 210 for specifying date ranges Added ISO19115CD2 doctype Z39.50 Improvements Isite Z39.50 clients handle ReferenceID parameters and have configurable timeouts Improved handling of user authentication information in Isite Z39.50 clients

20. Isite General Enhancements Isite/Isearch2 ported to Solaris and Cygwin zserver writes its process ID to a file, ala Apache Can search multiple fields in single query term (title+abstract/water) Can search multiple fields from one use attribute Improved Isearch-cgi, with support for numeric, spatial and temporal searches, and configuration file Virtual naming for indexes Improved documentation using SGMLdoc Updated class documentation

21. INFEO Client to Isite Server INFEO is a European Space Agency operated imagery catalog service using the CIP Profile of Z39.50 Testing in collaboration with Maurice Klein Gebbinck at ESA Spatial searching works but… Isite supports only BoundingCoordinates use attributes (2060 and 3111) GEO term ordering is different than that used by INFEO Semantics of spatial relations are not consistent

22. CIP Client to Isite/GEO Server Isite supports full-text queries using the Any use attribute (1016), not implemented in some CIP clients Some presentation issues in clients

23. Isite/GEO Clients to CIP Server User Authentication Issues Isite does not require authentication information unless it is required for access. Indeed, interoperability testing with other servers generated significant problems in such cases ReferenceID Issues This is an optional parameter in the Z39.50 standard By default, Isite clients omit it Specifying a value crashes the Blue Angel MetaStar server – reported to Blue Angel Omitting a value fails to connect to INFEO’s CIP server

24. FGDC and ISO 19115 FGDC is prototyping support for ISO 19115 metadata The intention is to use the abstraction layer provided by Z39.50 to make ISO metadata queryable as if it were FGDC metadata In this way, ISO metadata does not have to be transformed into the standard FGDC XML format Configuration files in Isite define the mapping between the GEO 2.2 profile use attributes and one or more specific fields in the ISO metadata

25. Presenting ISO Results Valid XML means we can build results of various sorts using stylesheet transformation tools like Xalan or Apache Cocoon From one XML document, it is possible to create results on demand – FGDC Brief and Summary element sets in any/all of SUTRS, XML, HTML, USmarc XSLT may be difficult and tedious for XML that is as complex as ISO 19115

26. GeoConnect v1.0.2 – An Update for the Clearinghouse WG Bruce Westcott SMMS Metadata Consultant

27. GeoConnect Metadata Server What does GeoConnect do? What are the pre-requisites and components of GeoConnect? How do you obtain GeoConnect and support/updates? What are key features?

28. What does GeoConnect Do? Stores FGDC-standard metadata in a relational database (Access, MS-SQL or Oracle); Supports FGDC, Bio.Profile, and unlimited User- Defined fields; Provides a sophisticated GUI for content management and external metadata import; Provides an “out of the box” web page for searching “live” metadata in the database, and Administrator GUI for managing the web page ( ”live” examples at http://www.intergraph.com/gis/smms/geoconnect/gc_action.asp ); http://www.intergraph.com/gis/smms/geoconnect/gc_action.asp Provides a Z39.50 Clearinghouse server application.

29. What are GeoConnect Components? Database Scripts – Create structures in Oracle or MS-SQL & an ODBC connection MetaWeb – Use GeoConnect ASP code (as is or modified for your web page) to provide Intranet or Web access Z39.50 Server – Create a server process to access the database and respond to Clearinghouse queries GeoConnect Administrative Tool – (MetaWeb only) Manage your Web GUI

30. What are GeoConnect Pre- requisites? Client machine (data loading and Web site management): Win98, Win2K, WinNT GeoConnect server: Win-NT Server (or equivalent) Microsoft IIS 4 with ASP (required for MetaWeb application only) Oracle 8.0+ or MS-SQL Server v7 or v2000 GeoMedia products are not required

31. How do you obtain GeoConnect and support? Applications and Documentation (PDF) distributed on SMMS CD -- order online at http://www.intergraph.com/gis/smms/default.asp http://www.intergraph.com/gis/smms/default.asp Updates, knowledge base, and technical documents available at http://www.intergraph.com/gis/support/smms.asp http://www.intergraph.com/gis/support/smms.asp Intergraph Premium Maintenance: Web-based and phone-based support Automatic software “hot-fixes” and upgrades

32. What are Enhancements in this Version? Fully compatible with Geo2.2 Profile for Z39.50 Certified on newer versions of Win-OS and RDBMS products Increased server process stability More user-customization features

33. The GeoConnect Architecture Z39.50 Queries

34. Goals for the ArcIMS Metadata Server Provide the capability to manage and search a central metadata repository over the Internet. Allow data producers to easily publish their metadata to the repository. Allow data consumers to easily search the metadata in the repository.

35. Adding support for metadata to ArcIMS Provides a single set of enhanced metadata functionality for use by: The Geography Network ArcInfo 8.x ArcSearch ArcExplorer 3.x Other custom client applications

36. New in ArcIMS 4.0.1 Z39.50 Support Metadata Harvesting Increased performance for Metadata Server Improved ISO support

37. Internet ArcSDE Z39.50 Z39.50 Connector ArcCatalog Metadata Explorer Clearinghouse ArcXML ArcIMS Z39.50 ArcXML

38. Why the Metadata Server? Provides a central metadata repository that keeps track of all your data, wherever it may be, and whatever format it is. Allows users on any platform to quickly search for data by extent, keyword, or other criteria using a lightweight web app. Integrated with ArcGIS clients, allowing you to publish, manage, and search metadata using familiar tools and interfaces. Distributed and scalable, allowing networks of servers to be searched with a single request. Essential backend product that allows organizations to build their own geography network.

39. Enraemed Metadata Software

40. Develop by Dutch Donor Agency for the Ethiopian Government Being used within Ethiopia by all governmental institutions Willingness to hand over software to UNEP and GSDI/FGDC for maintenance

41. Enraemed Metadata Software Features ISO, FGDC, GILS, and DC compliant Stand Alone or Client–Server Backend Database MSDE, MS SQL Server, Access2000 Globally unique IDs Element Navigator Elements of selected standard Mandatory-optional-mandatory Jump function

42. Enraemed Navigator

43. Enraemed plans Continue evaluation of software as replacement for MetaLite reference implementation software Attend in-depth training in November on- site to learn programming details Develop/modify basic package for use in US and elsewhere as metadata collector

44. Metadata Status Contract to Intergraph to build XSLT transformation rules to translate FGDC V2 as XML into ISO 19115 as XML – awaiting newer version and confirmation of transform assumptions ISO 19115 Metadata Standard will have a companion Technical Specification on how it will be encoded in XML Both to be approved, hopefully, by mid 2003

45. Denver Workshop Summary zAbout 150 people attended a three day SDI workshop hosted by US and Canada zParade of relevant standards and specifications and policies and technical solutions providers zRaised some issues and concerns about how NSDI could be improved

46. Clearinghouse Suggestions Show benefits of migration to ISO 19115 metadata, minimize pain of transition/ participation Provide an alternative solution to the Z39.50 approach to Clearinghouse search using search engine approach Make Clearinghouse searches easier and more reliable Adopt the Canadian approach of web components to allow anyone to build a Gateway
