19115-1 Geospatial metadata profile - Margie Smith (Geoscience Australia)

  2. 2. GeoNetwork Community of Practice - 2017 ISO 19115-1 – What’s new and what’s different ISO 19115:2003 Metadata ISO 19119:2005 Services Metadata ISO 19139:2007 XML Encoding ISO 19115-1:2014 Metadata Fundamentals & Services ISO 19115-3:2016 XML Encoding (F&S) ISO 19157:2013 Data Quality Metadata ISO 19157-2 Data Quality XML Encoding ISO 19115-2:2009 Metadata-Imagery ISO 19115-2 Rev Metadata-Imagery OGC Services ISO 19119:2016 Services Metadata OGC Services ISO 19139-2:2012 XML Imagery Encoding (?) ISO 19115-4 (?) XML Imagery Encoding
  3. 3. GeoNetwork Community of Practice - 2017 Standard Description ISO 19115-1:2014 Information about identification, extent, quality, spatial and temporal aspects, content, spatial reference, portrayal, distribution, and other properties of digital geographic data and services ISO 19115-3:2016 Integrated XML implementation of ISO 19115-1, ISO 19115-2, and concepts from ISO 19139 ISO 19115-2 (under revision) Extension of the ISO 19115 for imagery and gridded data; Information about properties of measuring equipment used to acquire data, geometry of measuring process employed by equipment, and production process used to digitize raw data. This extension deals with metadata needed to describe the derivation of geographic information from raw data, including the properties of the measuring system, and numerical methods and computational procedures used in derivation. ISO 19139-2:2012 XML Schema implementation derived from ISO 19115-2 ISO 19157:2013 Information describing the quality of geographic data: components for describing data quality; components and content structure of a register for data quality measures; general procedures for evaluating the quality of geographic data; principles for reporting data quality. ISO 19157-2:2016 XML schema implementation derived from ISO 19157:2013 and the data quality related concepts from ISO 19115-2 ISO 19119:12016 Technical service specifications, defines requirements for how platform neutral and platform specific specification of services shall be created, in order to allow for one service to be specified independently of one or more underlying distributed computing platforms
  4. 4. Implementation of the GA Metadata Profile GA Metadata Profile of the ISO 19115:2003: • Based on the ANZLIC metadata profile • Facilitate interoperability between the GA datasets and make it easier to find, use and share GA data and other resources • Change element obligations to ensure consistency and compliance with legal and business requirements: • Mandatory elements: Constraints, Format, Lineage, Maintenance, Source, Format (storage +/- distribution), Keywords (ANZRC) • Conditional elements: Distribution, Spatial and Temporal Extent GeoNetwork Community of Practice - 2017
  5. 5. Implementation of the ISO 19115-1 in GA • Cross-walk between 19115 and 19115-1 and metadata transfer • Use GeoNetwork for metadata creation, edit and search • GA Metadata Profile of the ISO 19115-1:2014 (in development) • Improved capture of resource and metadata constraints • Introduction of Services Metadata – mandatory for services, user guide • Recorded link between datasets and services • Recording horizontal linkages between resources • Standardised keywords (in progress) GeoNetwork Community of Practice - 2017
  6. 6. Implementation of the ISO 19115-1 in GA • Cross-walk between 19115 and 19115-1 and metadata transfer • Use GeoNetwork for metadata creation, edit and search • GA Metadata Profile of the ISO 19115-1:2014 (in development) • Improved capture of resource and metadata constraints • Introduction of Services Metadata – mandatory for services, user guide • Recorded link between datasets and services • Recording horizontal linkages between resources • Standardised keywords (in progress) GeoNetwork Community of Practice - 2017
  7. 7. OGC Standards and GeoNetwork at GA • GA provides access to its corporate product catalogue using GeoNetwork’s OGC CSW 2.0.2 interface • http://ecat.ga.gov.au/geonetwork/srv/eng/csw • Accords with GA’s strategy of adopting open standards to enable interoperability • Several organisations routinely harvest GA’s corporate product catalogue using CSW: • data.gov.au • Australian National Data Service (ANDS) • Australian Ocean Data Network (AODN) • Trove - National Library of Australia • NCI • GA leverages the CSW capabilities of the corporate product catalogue for in-house developed systems : • GA’s Data and Publication Search tool • Tools for GA geophysicists to discover and access GA’s geophysical data holdings
  8. 8. • GeoNetwork’s virtual CSW capability is used to expose GA’s service metadata as a service catalogue: • http://ecat.ga.gov.au/geonetwork/srv/eng/csw-services • GA has adopted the new ISO 19115-1:2014 metadata standard. Most users require the metadata in the old ISO 19115:2003 standard. GeoNetwork’s CSW can perform dynamic conversions to other formats. • ISO have published an XSLT for conversion of ISO 19115-1:2014 to ISO 19115:2003, which is implemented in GA’s GeoNetwork CSW. • OGC’s ISO Metadata Application profile for CSW 2.0.2 is specifically written for ISO 19115:2003. • The ISO 19115-3 schema plugin to GeoNetwork has so far been adequate in adapting the CSW to work with the new ISO 19115-1:2014 standard • Are there plans within OGC to develop a revised application profile of CSW for the new ISO 19115-1:2014 standard?
