Linking website, web services, … using URL

This section applies mainly to ISO19139 records and partially to Dublin Core (ie. only documents can be associated in Dublin Core) standards.

Linking a document

2 approaches can be used to link documents:

  • by providing a URL
  • by uploading a document

To add a new one, click on the + caret button then Add an online resource button or, if alreay one exists, just click on the title of the Online resources.


To link a URL, set the following properties:

  • Protocol to describe the type of document attached (Web address (URL) is the default)
  • Linkage to point to the target document. It can be any type of links like http://, ftp://, file:///, …
  • Name is optional and provides a label for making an hyperlink
  • Description is optional and provides more details about the link

To upload a document, switch to the Upload tab and choose a document, or drag and drop it in the pop up. In that case, the protocol is hidden and is set to WWW:DOWNLOAD.


Depending on your needs, more specific links could be added and will be associated to different actions and display in the applications.

Linking a WMS layer

To be able to view a record on the map viewer, it may be relevant to add a reference to one or more WMS services publishing the dataset. An online resource is encoded using the following in ISO19139:

<gmd:onLine xmlns:gmd=""
         <gco:CharacterString>Subdivision de section cadastrale (Plan cadastral informatisé du Grand Lyon)(OGC:WMS)</gco:CharacterString>

To add a WMS layer:

  • choose the protocol OGC:WMS Web Map Service,
  • set the URL of the service,
  • then the wizzard query the service to retrieve the list of layers
  • choose one or more layer in the list or set it manually.

Linking a database table or a GIS file on the network

To reference a GIS file or a database table, user can upload or link to a that resource (see Linking a document). The type of protocol depends on the type of resource associated:

Type of resource Vector file uploaded (eg. zipped Shapefile)
URL File URL created after upload on the catalog. eg. http://localhost:8080/geonetwork/srv/eng/resources.get?id=1631&
Nom File name (readonly)
Type of resource Vector file on the network
URL File path. eg. file:///shared/geodata/world/hydrology/rivers.shp
Nom Description du fichier
Type of resource Vector (Table PostGIS)
URL jdbc:postgresql://localhost:5432/login:password@db
Protocole DB:POSTGIS
Nom Table name

When having information about the database or file on the local network, it may be relevant to hide those informations for public users (see Restricting information to metadata sections).
