  • Aleta Vienneau

2
Leveraging Metadata Standards in ArcGIS for
Interoperability
  • Metadata standards why, what, and when
  • Why metadata and metadata standards
  • Status of metadata standards and profiles
  • Creating standards-compliant metadata in ArcGIS
  • ArcGIS notes for all standards and profiles
  • FGDC CSDGM metadata
  • ISO 19139 metadata
  • North American Profile (NAP)

Metadata standards why, what, and when
4
Usefulness and utility of released data rating
system
Data is released (PDF of scanned paper)
Data is structured, in machine-readable format (Excel file)
Data is in an open file format (CSV file)
Data uses consistent format, discoverability methods and metadata associations
Data uses URLs to identify things
Data is linked to other linked data
5
Why is geospatial metadata important?
  • Geospatial data is an imperfect abstraction of
    the real world
  • A model, a point of view
  • Assumptions, limitations, approximations,
    simplifications
  • Ensures we understand the geographic information
  • The producer is not usually the user
  • Supports good information management
  • Geospatial resources are valuable
  • Reuse
  • Oh yeahit helps us find the right information
    for the right purpose

6
Why use metadata standards?
  • Provide resource producers an idea of the
    metadata they should collect
  • Provide consistent terminology for global search
  • Provide an common understanding of data around
    the Globe and across information communities

7
Regional and national standards from the mid
1990s

  • Australia New Zealand Core metadata elements
    for land and geographic directories in Australia
    and New Zealand

Changes coming to ISO 19115 and ISO 19139
  • Today
  • ISO 19115 defines content
  • ISO 19139 defines encoding rules and the encoding
    (XML schema)
  • Encoding rules define how to create XML Schema
    from UML
  • Future
  • ISO 19115-1 defines improved content
  • ISO 19115-3 defines encoding (XML schema)
  • Revise ISO 19139 to define encoding rules only

11
Schedule of standards work in progress

  • XML Schema
  • XSLT to convert from ISO 19115/19139 format to
    the ISO 19115-1/19115-3 format
  • And back
  • Schematron

14
Future planned standards work
  • ISO 19139 revision to contain encoding rules only
  • ISO 19157-2 XML encoding for data quality
  • Renumber ISO 19139-2 Metadata XML encoding for
    imagery and gridded data becomes ISO 19115-4

15
North American Profile of ISO 19115 (NAP)
  • NAP is a profile of ISO 19115 Metadata
  • Remains stable as-is
  • U.S. will focus on transition to 19115-1 using
    NAP as a guide
  • After gaining experience with 19115-1, will work
    with Canada to update NAP as a profile of 19115-1

16
Creating standards-compliant metadata in ArcGIS
17
ArcGIS notes for all standards and profiles
  • Upgrade existing metadata to the ArcGIS metadata
    format
  • Let ArcGIS automatically update metadata
  • Important Help topics
  • The ArcGIS metadata format
  • Creating standard-compliant metadata
  • Let 10.1 validation rules in the editor guide you
  • Validation rule updates coming with 10.1 SP1

18
FGDC CSDGM metadata
  • Creating FGDC CSDGM metadata is fully supported
    with ArcGIS 10.0 SP4
  • All FGDC metadata content upgraded to ArcGIS
    metadata
  • Continue to apply service packs as they are
    available
  • Create metadata in the Description tab

19
FGDC CSDGM metadata
  • Set CSDGM style, and check options in Options
    dialog box

20
FGDC CSDGM metadata
  • View 9.3.1 FGDC CSDGM-format metadata
  • Popup warns you an upgrade is needed
  • Yes upgrade right away
  • No do it later with Upgrade button or Upgrade
    Metadata tool
  • FGDC CSDGM-format content appears at the bottom
    of display
  • Click FGDC Metadata (read-only) heading
  • Content is read-only in the context of the
    Description tab

21
FGDC CSDGM metadata

  • Illustrated guide to complete FGDC metadata
  • Differences between ArcGIS metadata and FGDC
    metadata
  • New topic in 10.1 online Help

22
FGDC CSDGM metadata
  • Locate specific elements with the illustrated
    guide

23
FGDC CSDGM metadata
  • Let ArcGIS automatically update metadata
  • Required to include spatial reference in exported
    metadata
  • Some content controlled by the metadata style
  • Dont type Noneadded on export
  • Process steps ordered by date on export

24
FGDC CSDGM metadata
  • Export button creates a CSDGM-formatted XML file
  • Use exported XML and USGS MP Metadata Translator
    tool to produce additional file formats
  • Import button converts a CSDGM-formatted XML file
    to the ArcGIS metadata format
  • Transform a CSDGM-format text file to XML format
    with mp using a Python script, then import XML

25
FGDC CSDGM metadata
  • 10.1 editor validates ArcGIS metadata content
    against CSDGM rules as you type
  • Improvements to the rules coming with 10.1
    service pack 1
  • Validate button creates a CSDGM-formatted XML
    file and validates it with the FGDC DTD
  • Export metadata to a CSDGM XML file, then
    validate it with mp using USGS MP Metadata
    Translator tool

26
FGDC CSDGM metadata
  • Can remove FGDC CSDGM-format metadata using
    geoprocessing model and provided XSLT
  • remove pre94 metadata elements.xslt

27
ISO 19139 metadata
  • Set ISO 19139 style and check options in Options
    dialog box

28
ISO 19139 metadata
  • Use ArcGIS 10.0 SP4 or later
  • Creating ISO 19139 metadata incorporates both ISO
    19115 content and ISO 19119 content

29
ISO 19139 metadata
  • If you created 9.3.1 metadata using ISO wizard
    only, metadata is upgraded automatically when you
    edit it and save changes in the Description tab
  • If you created 9.3.1 metadata using both the ISO
    and FGDC editors, choose if you want to upgrade
    FGDC or ISO
  • Make definitive choice by running Upgrade
    Metadata tool

30
ISO 19139 metadata
  • Export button in the Description tab creates an
    ISO 19139-formatted XML file
  • Import button in the Description tab converts an
    ISO XML file to the ArcGIS metadata format

31
ISO 19139 metadata
  • Validate ArcGIS metadata according to ISO 19139
    rules as you type in the editor
  • The rules as defined in the ISO 19115 and ISO
    19119 standard documents
  • Validate button in the Description tab creates an
    ISO 19139-formatted XML file and validates with
    online XSDs
  • URL we use for online XSDs will be changing in
    the future

32
ISO 19139 metadata
  • Can remove 9.3.1-formatted metadata using
    geoprocessing model and provided XSLT
  • remove pre94 metadata elements.xslt

33
North American Profile (NAP)
  • Set NAP style and check options in Options dialog
    box

34
North American Profile (NAP)
  • Essentially the same as creating ISO 19139
    metadata
  • Additional codelist values available in the
    editor
  • NAP-specific rules in the editor
  • Content not included in NAP is not available in
    the editor unless it is considered part of a
    complete ArcGIS metadata document

35
North American Profile (NAP)
  • Export button in the Description tab creates an
    ISO 19139-formatted XML file
  • If edits were saved using the NAP style, exporter
    ensures codelist values and content are
    appropriate for NAP
  • Import button in the Description tab converts an
    ISO 19139 XML file to the ArcGIS metadata format
  • ISO importer that supports NAP-specific content
    will be available in a future 10.1 service pack

36
North American Profile (NAP)
  • Validate ArcGIS metadata as you type according to
    NAP rules
  • Validate button in the Description tab creates an
    ISO 19139-formatted XML file and validates with
    online XSDs
  • No NAP-specific XSDs

37
INSPIRE Metadata Directive
  • Set INSPIRE style and check options in Options
    dialog box

38
INSPIRE Metadata Directive
  • Provide the ability to create ISO metadata that
    conforms to the INSPIRE Metadata Directive
  • Essentially the same as creating ISO 19139
    metadata
  • Limited codelist values in the editor as
    appropriate
  • INSPIRE-specific rules in the editor

39
INSPIRE Metadata Directive
  • Export button in the Description tab creates an
    ISO 19139-formatted XML file
  • If edits were saved using INSPIRE style, exporter
    ensures codelist values and content are
    appropriate for INSPIRE
  • Import button in the Description tab converts an
    INSPIRE-compliant ISO 19139 XML file to the
    ArcGIS metadata format

40
ANZLIC and other ISO profiles
  • Complete ISO 19139 content is supported with the
    ISO 19139 metadata style
  • As long as you know the rules for your profile,
    you can create metadata conforming to that
    profile in ArcGIS
  • Can use the ArcGIS Metadata Toolkit to customize
    the ArcGIS metadata editor for your profile
  • Can run Schematrons based on XSLT 1.0 in ArcGIS
    as an XSLT

41
Customizing the metadata editor
  • Create a custom metadata style for a specific
    profile
  • Download the ArcGIS Metadata Toolkit from
    support.esri.com
  • Documents the ArcGIS metadata format
  • Instructions for creating a custom metadata style
  • Code for all pages in the metadata editor
  • A WPF application with XAML forms written in C
  • Sample project for adding a custom page
  • Instructions for customizing export
    transformations

42
Multilingual metadata
  • ArcGIS lets you work with one language at a time
  • Two methods are described in ISO standard
    documents for creating multilingual metadata
  • Recommend creating a second XML document
    containing written content in a second language
  • Devise and stick with a naming convention
  • Indicate in metadata that information is
    available for another locale
  • Cross-reference the additional XML file in the
    items metadata
