  18. 18. Resource discovery metadata <ul><li>is information in a structured format describing a resource or a collection of resources. </li></ul><ul><li>Metadata not only helps find resources and data, but it then indicates how to interpret and use the data. </li></ul><ul><li>Publishing metadata facilitates data sharing between organizations and stimulates cooperation and a coordinated, integrated approach to policy issues. </li></ul><ul><li>GIS metadata has a spatial component such as the extent of the earth's surface the data covers. </li></ul><ul><li>Metadata can describe GIS data, a GIS Web service, or an online metadata catalogue. </li></ul>J Regan 12/2/2010 SLA Seminar Pune, India

  45. 46. 12 February 2010 JRegan SLA Seminar Pune AusDIN Portal
  46. 47. 12 February 2010 JRegan SLA Seminar Pune About AusDIN <ul><li>The Australian Disaster Information Network </li></ul><ul><li>(AusDIN) </li></ul><ul><ul><li>established to facilitate a whole of government approach to Emergency Management, across the three tiers of Australian government. </li></ul></ul>
  47. 48. 12 February 2010 JRegan SLA Seminar Pune The AusDIN Portal <ul><li>Provides a mechanism to index and link to disparate emergency management websites, documents and other information resources </li></ul>
  48. 49. 12 February 2010 JRegan SLA Seminar Pune Behind the web interface... The Emergency Management Metadata Application Profile i.e. a subject specific profile of a metadata standard for an application (database)
  49. 50. 12 February 2010 JRegan SLA Seminar Pune Purpose of the Profile: <ul><li>To support Data Harmonisation which enhances </li></ul><ul><ul><li>access, sharing, reuse and repurposing of data </li></ul></ul><ul><ul><li>information resources and services </li></ul></ul>
  50. 51. 12 February 2010 JRegan SLA Seminar Pune The lack of standardisation throughout Australia, in the area of Emergency Management information resources, poses an increasing number of problems in our ability to search, find and retrieve relevant and/or the specific resources. Current issues:
  51. 52. 12 February 2010 JRegan SLA Seminar Pune
  52. 53. 12 February 2010 JRegan SLA Seminar Pune Relationship between the standards used
  53. 54. 12 February 2010 JRegan SLA Seminar Pune The Emergency Management Metadata Application Profile <ul><li>Designed to facilitate the use of properties </li></ul><ul><ul><li>for the implementation of database applications </li></ul></ul><ul><ul><li>by individual organisations and subject specialists </li></ul></ul><ul><ul><li>within the Emergency Management Sector </li></ul></ul>
  54. 55. Why not use the ANZLIC Profile? <ul><li>ANZLIC is especially relevant for use with datasets </li></ul><ul><li>Many mandatory elements </li></ul><ul><li>Most users do not acknowledge that this amount of detail is required especially for general resource discovery purposes </li></ul>12 February 2010 JRegan SLA Seminar Pune
  55. 56. 12 February 2010 JRegan SLA Seminar Pune The Profile includes properties in the following three groups: 15 properties about the resource or service being described, and 8 properties that describe the metadata record. (see Administrative metadata below) 11 properties about spatial datasets and data. The Emergency Management Metadata Application Profile
  56. 57. 12 February 2010 JRegan SLA Seminar Pune Non-Geographic Datasets <ul><li>The core set of AGLS metadata about a resource includes: </li></ul><ul><ul><li>Title </li></ul></ul><ul><ul><li>Date </li></ul></ul><ul><ul><li>Creator </li></ul></ul><ul><ul><li>Availability </li></ul></ul><ul><ul><li>Identifier </li></ul></ul><ul><ul><li>Description </li></ul></ul>
  57. 58. 12 February 2010 JRegan SLA Seminar Pune Administrative metadata (metadata about metadata) <ul><li>These details assist in understanding how the record may need to be interpreted when being reused, such as when data is transferred to another database.They include: </li></ul><ul><ul><li>Metadata file identifier </li></ul></ul><ul><ul><li>Metadata language </li></ul></ul><ul><ul><li>Metadata character set </li></ul></ul><ul><ul><li>Metadata point of contact </li></ul></ul><ul><ul><li>Metadata date stamp </li></ul></ul><ul><ul><li>Metadata standard name </li></ul></ul><ul><ul><li>Metadata standard version </li></ul></ul>
  58. 59. 12 February 2010 JRegan SLA Seminar Pune Geographic Datasets By using the core metadata recommended in the ANZLIC Profile interoperability will be enhanced, allowing users to understand without ambiguity the geographic data and the related metadata provided by either the producer or the distributor.
  59. 60. 12 February 2010 JRegan SLA Seminar Pune <ul><li>Contains metadata answering the following questions: </li></ul><ul><ul><li>‘ Does a dataset on a specific topic exist (“what”)?’ </li></ul></ul><ul><ul><li>'For a specific place (“where”)?’ </li></ul></ul><ul><ul><li>'For a specific date or period (“when”)?’ </li></ul></ul><ul><ul><li>'A point of contact to learn more about or order the dataset (“who”)?’ </li></ul></ul>Geographic Datasets
  60. 61. 12 February 2010 JRegan SLA Seminar Pune Geographic Datasets <ul><li>The properties in this category are: </li></ul><ul><ul><li>Dataset title </li></ul></ul><ul><ul><li>Dataset reference date </li></ul></ul><ul><ul><li>Abstract describing the data </li></ul></ul><ul><ul><li>Dataset responsible party </li></ul></ul><ul><ul><li>Spatial representation type </li></ul></ul><ul><ul><li>Spatial resolution of the dataset </li></ul></ul><ul><ul><li>Dataset topic category </li></ul></ul><ul><ul><li>Geographic location of the dataset (by four coordinates or by description) </li></ul></ul>
  61. 62. 12 February 2010 JRegan SLA Seminar Pune Geographic Datasets <ul><li>And </li></ul><ul><ul><li>Dataset language </li></ul></ul><ul><ul><li>Dataset character set </li></ul></ul><ul><ul><li>Metadata file parent identifier </li></ul></ul>
  62. 63. 12 February 2010 JRegan SLA Seminar Pune Obligation levels for properties Mandatory : these properties must be present in all metadata records; Conditional : these properties must be present under certain circumstances; Recommended: there may be valid reasons in particular circumstances not to include these properties, but the full implications must be understood and carefully weighed; and Optional : these properties are truly optional

  64. 65. 12 February 2010 JRegan SLA Seminar Pune Metadata Property description (cont)
  65. 66. 12 February 2010 JRegan SLA Seminar Pune Crosswalks between standards <ul><li>A crosswalk or mapping , identifies which 'tag' or 'element' or 'property' in one standard relates to one in the second standard </li></ul><ul><li>AGLS and ANZLIC identified this issue for the interoperability some years ago. </li></ul><ul><li>Version 2 of the mapping is now available http://www.osdm.gov.au/Metadata/ANZLIC+metadata+resources/default.aspx </li></ul>

Encoding this information in RDF allows it to be passed between computer applications in an interoperable way. </li></ul><ul><li>Using RDF also allows knowledge organization systems to be used in distributed, decentralised metadata applications. Decentralised metadata is becoming a typical scenario, where service providers want to add value to metadata harvested from multiple sources. </li></ul>JRegan SLA Seminar Pune
