GCube Data Catalogue for GRSF

GCube Data Catalogue: support for GRSF

In this page are reported the relevant information about the GRSF Data Catalogue, which is available here. This page is somehow an extension of the main gCube Data Catalogue guide, you are suggested to read before continue.

The GRFS Data Catalogue stores, as well as allows the publication of products of two types: Stock and Fishery. Apart from the default set of metadata, each type of product will also have specific fields. Some of them will also become automatically tags of the product. The same reasoning applies for group associations. In fact a set of groups was already available and each product will be automatically associated to them during publication, if that is the case. Fields that fire tags creation or groups association are documented below.

The publication phase is performed by means of a RESTful service whose publish methods accept JSON objects. The service allows also to publish records belonging to the original source records (i.e., "RAM", "FishSource" and "FIRMS") on which the aggregated GRSF records are build.

Metadata

Common Metadata

The following table shows the set of core metadata, that is the ones shared by both Stock and Fishery types. Some of them are automatically filled. The values given to some fields are automatically used to tag the product. Check the 'Is Tag' column of the table below. Other fields have a controlled vocabulary (that is, they can assume values selected from a defined set), and the value assigned to these fields allow to automatically determine to which group assign the product. Check the 'Is Group' column below.

The table also reports the column Type that shows how the field is mapped into the product, once it is published within the catalogue, i.e. as a simple field (key/value pair, possibly repeatable) or a resource (an object with a mandatory name, an optional description and a mandatory url).

IMPORTANT: Any other field that doesn't match one of the below ones will be managed as an object having a key and a value, both of String type, and attached to the product as a simple field.

GRSF Publication Web Service

Records publication is performed by means of a RESTful web service running over SmartGears. Almost every call to the service requires the security token of the user for the context in which he/she wants to publish or exploit the other functionalities. Please note that in case of product publication it is needed that the user has enough privileges. The list of roles and associated privileges for the catalogue users is reported here. The VRE Manager assignes them.

In order to retrieve your security token you can use the token generator portlet.

The right address for contacting the GRSF service in a context can be discovered by means of the Information System . You need the following parameters

Service Name = GRSFPublisher
Service Class = Data-Catalogue
Entry Name = jersey-servlet

For testing purpose, a running instance can be contacted at the following address

https://smart-grsf-d-d4s.d4science.org/grsf-publisher-ws/rest/  [GRSF_PUBLISHER_WS_BASE_URL]

The token for testing purpose can be retrieved from the VRE at this url https://next.d4science.org/group/nextnext/home (register yourself if needed). In the following, every time you perform a request you must specify the type of record for which it will be valid, i.e., in the request path you need to specify a value among:

• grsf;
• fishsource;
• ram;
• firms.

Check Service Availability

To check that the stock/fishery service is up and running, just put the url below in your browser

[GRSF_PUBLISHER_WS_BASE_URL]/{...}/fishery/hello

Specify the record type by replacing {...}. The response should look like

Hello.. Fishery service is here

or

[GRSF_PUBLISHER_WS_BASE_URL]/{...}/stock/hello

and the response should look like

Hello.. Stock service is here

Retrieve the licenses list

The default license that will be associated to the products, if not specified, is the CC-BY-SA-4.0 one. However, if it doesn't feet your needs, you can use one of the others available and retrievable by contacting the service(s) this way

[GRSF_PUBLISHER_WS_BASE_URL]/{...}/fishery/get-licenses?gcube-token=YOUR_TOKEN

or, for stock

[GRSF_PUBLISHER_WS_BASE_URL]/{...}/stock/get-licenses?gcube-token=YOUR_TOKEN

The response is a JSON object, containing couples <license key, license name>, which looks like

{
    "AFL-3.0": "Academic Free License 3.0",
    "RPSL-1.0": "RealNetworks Public Source License 1.0",
    "ODC-BY-1.0": "Open Data Commons Attribution License 1.0",
    "IPL-1.0": "IBM Public License 1.0",
    "ODbL-1.0": "Open Data Commons Open Database License 1.0",
    "PostgreSQL": "PostgreSQL License",
    "W3C": "W3C License",
    ....
}

During the publication phase, the identifier of the license chosen should be provided.

Stock Publication Example

The publish method to invoke to publish a stock for rams, grsf, fishsource or ram is the following

[GRSF_PUBLISHER_WS_BASE_URL]/{...}/stock/publish-product?gcube-token=YOUR_TOKEN

The JSON object you must provide in input has the following structure (of course, not all fields are mandatory)

{  
    "description":...,
    "license_id":...,
    "version":...,
    "maintainer":...,
    "maintainer_contact":...,
    "database_sources":[...],
    "source_of_information":[...],
    "uuid_knowledge_base":...,
    "traceability_flag":..,
    "data_owner":...,
    "type":...,
    "stock_name":...,
    "stock_id":...,
    "stock_uri":...,
    "species":[...],
    "assessment_distribution_area":[...],
    "exploiting_fishery":[...],
    "management_entity":...,
    "assessment_methods":...,
    "state_of_marine_resource":...,
    "standard_exploitation_rate":[...],
    "standard_abundance_level":[...],
    "water_area":[...],
    "narrative_state_and_trend":...,
    "scientific_advice":...,
    "reporting_entity":...,
    "reporting_year":...,
    "status":...,
    "short_title":...,
    "refers_to":[...]
}

The response of the method is a JSON object of this kind

{
   "id": ... , // identifier of the created product in the catalogue
   "knowledge_base_id" : .... // identifier of the product in the knowledge base
   "product_url": ..., // url of the created product
   "error": ... // in case of error, check this field
}

In case of success the HTTP code is 201 (CREATED) and the response contains the url and the unique identifier assigned to the product. In case of errors (BAD_REQUEST, INTERNAL_SERVER_ERROR, FORBIDDEN ... ) the "error" message of the above object reports what was wrong.

Example

A valid JSON, for example, is the following one

/*TODO*/

the response obtained from the service is

/*TODO*/

Fishery Publication Example

The publish method to invoke to publish a fishery product is the following

[GRSF_PUBLISHER_WS_BASE_URL]/{...}/fishery/publish-product?gcube-token=YOUR_TOKEN

The JSON object you must provide in input has the following structure (of course, not all fields are mandatory)

{
   "description": ...,
   "license_id": ...,
   "version": ...,
   "maintainer": ...,
   "maintainer_contact": ...,
   "catches_or_landings": [...],
   "database_sources": [...],
   "source_of_information": [...],
   "uuid_knowledge_base" : ...,
   "traceability_flag": ...,
   "short_title": ...,
   "refers_to":[...],
   "data_owner": ...,
   "reporting_year": …,
   "type": ...,
   "fishery_name": ...,
   "fishery_id": ...,
   "scientific_name": ...,
   "fishing_area": [...],
   "exploited_stocks": [...],
   "management_entity": ...,
   "jurisdiction_area": ...,
   "production_system_type": ...,
   "flag_state": ...,
   "fishing_gear": ...,
   "status": ...,
   "environment”: ...
}

The response of the method is a JSON object of this kind

{
   "id": ... , // identifier of the created product in the catalogue
   "knowledge_base_id" : .... // identifier of the product in the knowledge base
   "product_url": ..., // url of the created product
   "error": ... // in case of error, check this field
}

In case of success the HTTP code is 201 (CREATED) and the response contains the url and the unique identifier assigned to the product. In case of errors (BAD_REQUEST, INTERNAL_SERVER_ERROR, FORBIDDEN ... ) the "error" message of the above object reports what was wrong.

Example

A valid JSON, for example, is the following one

/* TODO */

the response obtained from the service is

/* TODO */

Delete a published product

If for some reason you need to delete a published product, you can invoke the following delete http methods. For fishery it is

[GRSF_PUBLISHER_WS_BASE_URL]/{...}/fishery/delete-product?gcube-token=YOUR_TOKEN

whereas for stock

[GRSF_PUBLISHER_WS_BASE_URL]/{...}/stock/delete-product?gcube-token=YOUR_TOKEN

You must provide the identifier (returned back at creation time) of the product, in a JSON that looks like

{"id": "product-to-delete-identifier"}

The response status of the service, in case of success is 200 (OK)
