** THIS DOCUMENT IS A DRAFT **

gCube Data Catalogue.... using CKAN.

CKAN is a powerful data management system that makes data accessible – by providing tools to streamline publishing, sharing, finding and using data. CKAN is an open-source DMS (data management system) for powering data hubs and data portals. CKAN makes it easy to publish, share and use data see: http://ckan.org/

gCube Data Catalogue: Metadata

A Metadata in the gCube Data Catalogue is made by two parts: CKAN's default metadata fields and gCube Metadata Profile.


CKAN's default metadata fields

Those are metadata fields common for all metadata types in the gCube Data Catalogue (and used by default in the CKAN platform).

Label Field Name (API) Definition Guidelines Example
Title* title Name given to the dataset. Short phrase, written in plain language. Should be sufficiently descriptive to allow for search and discovery. Aquaculture Production and Consumption in Africa (2011)
Description description Short description explaining the content and its origins. Description of a few sentences, written in plain language. Should,provide a sufficiently comprehensive overview of the resource for anyone,to understand its content, origins, and any continuing work on it. The,description can be written at the end, since it summarizes key,information from the other metadata fields. This dataset contains attributes of aquaculture production and,consumption for each of Africa’s provinces in 2011. The data was,provided by………
Tags tags An array of Taxonomic terms stored as tags Taxonomic terms Access to education, Bamboo
License* lincese_title the license that applies to published dataset.
Organization* organization Organization the datasets belongs to See list of organizations on

https://ckan-d-d4s.d4science.org/organization

D4Science
Version version Version of dataset Increase manually after editing 1.0
Author* Owner of dataset The person who created the dataset in the format: Surname, Name Bloggs, Joe
Author Contact Contact details of owner The email or other contact details of the person who created the dataset. joe@example.com
Mantainer Mantainer of the dataset The person or the authority that maintains the dataset A person: Bloggs, Joe. An authority: D4Science

Contact details of mantainer The email or other contact details of the person who maintains the dataset. joe@example.com

mandatory fields are marked with an asterisk (*)

gCube Metadata Profile

gCube Metadata Profile defines a Metadata schema XML-based for adding custom metadata fields.

A gCube Metadata Profile is composed by one Metadata Format (<metadataformat>) that contains one or many (<metadatafield>). The schema is the following:

<?xml version="1.0" encoding="UTF-8">
<metadataformat>
    <metadatafield>
        <fieldName>Name</fieldName>
        <mandatory>true</mandatory>
        <isBoolean>false</isBoolean>
        <defaulValue>default value</defaulValue>
        <note>shown as suggestions in the insert/update metadata form of CKAN</note>
        <vocabulary>
            <vocabularyField>field1</vocabularyField>
            <vocabularyField>field2</vocabularyField>
            <!-- ... others vocabulary fields -->
        </vocabulary>
        <validator>
            <regularExpression>a regular expression for validating values</regularExpression>
        </validator>
    </metadatafield>
     <!-- ... others metadata fields -->
</metadataformat>

It's possible to validate a Metadata Format schema using following DTD


<?xml version="1.0" encoding="UTF-8"?>
<!ELEMENT metadataformat (metadatafield+)>
<!ELEMENT metadatafield (fieldName, mandatory, isBoolean?, defaulValue?, note?, vocabulary?, validator?)>
<!ELEMENT fieldName (#PCDATA)>
<!ELEMENT mandatory (#PCDATA)>
<!ELEMENT isBoolean (#PCDATA)>  <!-- MUST BE (true|false) -->
<!ELEMENT defaulValue (#PCDATA)> 
<!ELEMENT note (#PCDATA)> 
<!ELEMENT vocabulary (vocabularyField+)> 
<!ELEMENT vocabularyField (#PCDATA)> 
<!ELEMENT validator (regularExpression)> 
<!ELEMENT regularExpression (#PCDATA)> 

A possible instance of Metadata Field (<metadatafield>):

<metadatafield>
   <fieldName>Accessibility</fieldName>
   <mandatory>true</mandatory>
   <defaulValue>virtual/public</defaulValue>
   <vocabulary>
       <vocabularyField>virtual/public</vocabularyField>
       <vocabularyField>virtual/private</vocabularyField>
       <vocabularyField>transactional</vocabularyField>
   </vocabulary>
</metadatafield>

gCube Data Catalogue: Ckan Connector

gCube Data Catalogue: Geo Harvesting

This extension contains plugins like ckanext-geonetwork (and others) which add geospatial capabilities to CKAN.

Several harvesters to import geospatial metadata (like ISO 19139 format) into CKAN from other sources have been created in gCube Data Catalogue. In particular all metadata created into gCube Geonetwork (GeoNetwork is the catalog application to manage spatially referenced resources generated into D4Science Infrastructure) are harvested through the 'Geoentwork Resolver' a "middle tier" able to:

Mapping (among fields) from an ISO19139 Metadata to Ckan Dataset via ckanext-geonetwork is showed in the following table:

gCube Data Catalogue: Geo Datasets

In order to make a dataset queryable by location (geospatial dataset), a special extra must be defined, with its key named ‘spatial’. The value must be a valid GeoJSON geometry, for example:

{
  "type":"Polygon",
  "coordinates":[[[2.05827, 49.8625],[2.05827, 55.7447], [-6.41736, 55.7447], [-6.41736, 49.8625], [2.05827, 49.8625]]]
}

[Note: the polygon must be closed]

or

{
  "type": "Point",
  "coordinates": [-3.145,53.078]
}

GeoJSON Format Specification are available here: http://geojson.org/geojson-spec.html Datasets with spatial values are automatically geo-indexed, for example so that they can be searched using spatial filters.

GeoSpatial search for datasets: via API or Search Widget

Once your datasets are geo-indexed, you can perform spatial queries by bounding box (coordinates format is [LONG, LAT]), via the following API call:

/api/2/search/dataset/geo?bbox={minx,miny,maxx,maxy}[&crs={srid}]

If the bounding box coordinates are not in the same projection as the one defined in the database, a CRS must be provided, in one of the following forms:

    urn:ogc:def:crs:EPSG::4326
    EPSG:4326
    4326

Otherwise default bounding box is 4326. CKAN Wiki page for Legacy API

Moreover, you can perform spatial queries using an integrated map widget available on CKAN, which allows filtering results by an area of interest. You can try it on D4Science Data Catalogue
