Metadata¶

For questions and problems, contact rdm-contact@ufz.de

The SDI at UFZ provides an instance of GeoNetwork to publish metadata. In order to upload your data to GeoNetwork, mandatory metadata requirements must be fulfilled.

Before you start

If you want to use all functionality of the SDIs metadata workflows and have access to all needed components, you need to register first.

There are two options to provide the necessary metadata. You can either provide the metadata in a JSON-LD file via S3 or use the Admin-Frontend to create a metadata entry for GeoNetwork. In the second case, a JSON-LD will be created and stored in S3 with the corresponding data files. In both cases, it is possible to change the metadata through the Admin-Frontend.

OPTION 1: JSON-LD¶

Create a JSON-LD file (<filename>.jsonld)

One metadata file can describe a dataset of any amount of data files.
The data files do not need to have the same file format.
The metadata file must be uploaded to the root of the S3-directory where the corresponding data files are stored (see below)

- example-bucket
    - example-metadata.jsonld        >>> when uploaded here, all data in
           example-bucket will be included
           in the metadata record
    - example-dir-1
        - example-data-file-1           
    - example-dir-2
        - example-metadata.jsonld    >>> when uploaded here, all data in
           example-dir-2 will be included
           in the metadata record
        - example-dir-3
            - example-data-file-2
            - example-data-file-3
        - example-dir-4
            - ...

This is an example of a JSON-LD with all mandatory fields:

{
 "@context": {
  "@vocab": "https://schema.org/"
 },
 "@type": "Dataset",
 "version": "1.0",
 "inLanguage": "en",
 "encodingFormat": "xml, csv",
 "license": "EUPL 1.2",
 "name": "JSON-LD example",
 "identifier": [
  {
   "@type": "PropertyValue",
   "propertyID": "DOI",
   "value": ""
  },
  {
   "@type": "PropertyValue",
   "propertyID": "UUID",
   "value": ""
  }
 ],
 "dateCreated": "12.08.2024",
 "dateModified": "12.08.2024",
 "datePublished": "2024",
 "author": [
  {
   "@type": "Person",
   "givenName": "First Name",
   "familyName": "Family Name",
   "email": "email@ufz.de",
   "identifier": {
    "@type": "PropertyValue",
    "propertyID": "ORCID",
    "value": "https://orcid.org/XXXX"
   },
   "affiliation": {
    "@type": "Organization",
    "name": "Helmholtz Centre for Environmental Research",
    "identifier": {
     "@type": "PropertyValue",
     "propertyID": "ROR",
     "value": "https://ror.org/000h6jb29"
    }
   }
  }
 ],
 "publisher": {
  "@type": "Organization",
  "name": "Helmholtz Centre for Environmental Research",
  "identifier": {
   "@type": "PropertyValue",
   "propertyID": "ROR",
   "value": "https://ror.org/000h6jb29"
  }
 },
 "abstract": "This is an abstract",
 "keywords": [
  "keyword1",
  "keyword2"
 ]
}

The file can contain any amount of additional fields. However, these will be ignored in the S3-GeoNetwork-Workflow.

OPTION 2: Admin-Frontend¶

Go to https://web.app.ufz.de/gdi-backend/admin/ and log in.
Go to Metadata Records and select ADD METADATA RECORD.
Fill out the required fields.
Select SAVE.
(Optional) Go to GeoNetwork and check for your new metadata record.
