+# ISO 19115-3:2018 schema plugin
+
+This is the ISO19115-3:2018 schema plugin included in core-geonetwork.
+
+The main changes with the previous ISO19115-3 plugin are:
+* Update to latest XSD (https://github.com/ISO-TC211/XML/wiki/Schema-Updates)
+* Add support for 19115-2 Imagery standards
+
+
+## Reference documents:
+
+* http://www.iso.org/iso/catalogue_detail.htm?csnumber=53798
+* http://www.iso.org/iso/catalogue_detail.htm?csnumber=32579
+* https://github.com/ISO-TC211/XML/
+
+## Talks 
+
+* [Using the latest ISO Standard for
+Geographic Information (ISO19115-1)
+for an INSPIRE
+Discovery Service](http://cnig.gouv.fr/wp-content/uploads/2015/06/titellus_fx_prunayre_iso19115-3_inspire2015.pdf) (INSPIRE conference 2015)
+
+## Catalogue using ISO19115-3
+
+* SPW / Metawal http://metawal.wallonie.be/
+* Ifremer / Sextant https://sextant.ifremer.fr/ (only some projects - EMODnet Checkpoint, CERSAT)
+
+
+## Description:
+
+This plugin is composed of:
+
+* indexing
+* editing
+ * editor associated resources
+ * directory support for contact, logo and format.
+* viewing
+* CSW
+* from ISO19115-3 conversion
+* from ISO19115-2 conversion
+* from/to ISO19139 conversion
+* multilingual metadata support
+* validation (XSD and Schematron)
+
+## Metadata rules:
+
+### Metadata identifier
+
+The metadata identifier is stored in the element mdb:MD_Metadata/mdb:metadataIdentifier.
+Only the code is set by default but more complete description may be defined (see authority,
+codeSpace, version, description).
+
+```xml
+<mdb:metadataIdentifier>
+  <mcc:MD_Identifier>
+    <mcc:code>
+      <gco:CharacterString>{{MetadataUUID}}</gco:CharacterString>
+    </mcc:code>
+  </mcc:MD_Identifier>
+</mdb:metadataIdentifier>
+```
+
+### Metadata linkage ("point of truth")
+
+The metadata linkage is updated when saving the record. The link added points
+to the catalog the metadata was created. If the metadata is harvested by another
+catalog, then this link will provide a way to retrieve the original record in the
+source catalog.
+
+```xml
+<mdb:metadataLinkage>
+  <cit:CI_OnlineResource>
+    <cit:linkage>
+      <gco:CharacterString>http://localhost/geonetwork/srv/eng/home?uuid={{MetadataUUID}}</gco:CharacterString>
+    </cit:linkage>
+    <cit:function>
+      <cit:CI_OnLineFunctionCode
+         codeList="http://standards.iso.org/iso/19139/resources/codelist/gmxCodelists.xml#CI_OnLineFunctionCode"
+         codeListValue="completeMetadata"/>
+    </cit:function>
+  </cit:CI_OnlineResource>
+</mdb:metadataLinkage>
+```
+
+
+### Parent metadata
+
+The parent metadata records is referenced using the following form from the editor:
+
+```
+<mdb:parentMetadata uuidref="{{ParentMetadataUUID}}}"/>
+```
+
+Nevertheless, the citation code is also indexed.
+
+### Validation
+
+Validation steps are first XSD validation made on the schema, then the schematron validation defined in folder  [iso19115-3.2018/schematron](https://github.com/geonetwork/core-geonetwork/tree/master/schemas/iso19115-3.2018/src/main/plugin/iso19115-3.2018/schematron). 2 famillies of rules are available:
+* ISO rules (defined by TC211)
+* INSPIRE rules
+
+
+## CSW requests:
+
+If requesting using output schema http://www.isotc211.org/2005/gmd an ISO19139 record is returned. 
+To retrieve the record in ISO19115-3.2018, use http://standards.iso.org/iso/19115/-3/mdb/2.0 output schema.
+```xml
+<?xml version="1.0"?>
+<csw:GetRecordById xmlns:csw="http://www.opengis.net/cat/csw/2.0.2"
+  service="CSW"
+  version="2.0.2"
+  outputSchema="http://standards.iso.org/iso/19115/-3/mdb/2.0">
+    <csw:Id>cecd1ebf-719e-4b1f-b6a7-86c17ed02c62</csw:Id>
+    <csw:ElementSetName>brief</csw:ElementSetName>
+</csw:GetRecordById>
+```
+Note: outputSchema = own will also return the record in ISO19115-3.
+
+
+
+## More work required
+
+### Formatter
+
+
+### GML support
+
+* Polygon or line editing and view.
+
+### Imagery
+
+* Better support of mac:childOperation
