--------------------------------------
Summary: Update SIS to revision 2013 of the ISO 19115 standard
Key: SIS-94
URL: https://issues.apache.org/jira/browse/SIS-94
Project: Spatial Information Systems
Issue Type: Improvement
Components: Metadata
Reporter: Martin Desruisseaux
One of Apache SIS goals is to comply with the ISO (_International Standards
Organization_) specifications. Compliance to international standards not only
increase inter-operability between products, but is also a legal requirement
for government agencies in the European Union since the INSPIRE directive from
the European Commission.
Apache SIS currently implements the ISO 19115 (_Geographic information -
Metadata_) standard, as published in 2003, completed by ISO 19115-2 published
in 2009. The ISO organization updates their standards once every 10 years. The
new ISO 19115 revision is expected to be published around May 2013.
We will need to update Apache SIS to make it compliant with the new ISO 19115
standards. Because Apache SIS implements the GeoAPI interfaces defined by the
Open Geospatial Consortium (OGC), this task will need to be done in cooperation
with the OGC GeoAPI working group. More specifically, the tasks will be (not
necessarily in that order - many tasks are expected to be done in parallel):
* On the OGC GeoAPI side:
** Get legal copies of the new ISO 19115-1, -2, -3 and -4 standards (to be
provided by mentors).
** Review all classes, interfaces, fields and methods defined in the
{{org.opengis.metadata.*}} packages and compare them with the new definitions
provided in ISO 19115-1 and -2.
*** For every new elements added in ISO 19115-1/2, add the corresponding
elements in the Java interfaces.
*** For every elements removed from ISO 19115-1/2, deprecate the corresponding
elements in the Java interfaces.
*** Fix any discrepancies or errors which may be found on a case-by-case basis,
to be discussed on the GeoAPI mailing list.
*** Make sure that all elements have an up-to-date and accurate Javadoc.
** Update the GeoAPI specification with mentor help.
** Write test cases in the {{geoapi-conformance}} module.
* On the Apache SIS side:
** For all changes done in GeoAPI interface, reflect the changes in the Apache
SIS implementation in the {{org.apache.sis.metadata.iso.*}} packages.
** Add JAXB adapters for the new elements, or fix JAXB adapters for existing
elements, in order to marshal/unmarshall XML documents compliant with the new
standards as defined in ISO 19115-3 and -4.
** Check for any additional requirements defined by the INSPIRE directive.
** Ensure that Apache SIS passes the tests defined in GeoAPI.
** In collaboration with specialists, write some use cases and demos using the
new metadata objects.
Mentor for this task would be contributor of the Apache SIS metadata module and
GeoAPI chairman. Additional help can be obtained from an editor of some related
OGC specifications, and authors of the MD-Web project for more metadata advice.
