ledc.ugent.be:8828/list?pattern=.*ssn.*

Fetch all components for some PI, with transitive resolution of necessary sub-components

Parameters

property (required): the standardized name of the PI of interest

Output

A JSON document that includes all components available for this PI

Examples

ledc.ugent.be:8828/fetch?property=ledc.ugent.be/identifier%23issn:*

Measures the quality of a value for a given PI

Parameters

property (required): the standardized name of the PI of interest

value (required): a literal value for which the quality must be measured

Output

A JSON document that includes the result of the quality measurement: validity, quality level and an explanation

Examples

ledc.ugent.be:8828/measure?property=ledc.ugent.be/identifier%23issn:*&value=0165-0114

Transforms values of an input PI into values of an output PI

Parameters

from (required): the standardized name of the PI for which a value is given

to (optional): the standardized name of the PI for which a value is requested. If not specified, the 'to' property is assumed the same as 'from' and transformation becomes conversion to the standard format

value (required): a literal value on which the transformation is applied

Output

A JSON document that contains the result of the transformation

Examples

ledc.ugent.be:8828/convert?from=ledc.ugent.be/identifier%23issn:*&value=01650114

Scans valid instances of an input PI in a given text

Parameters

property (required): the standardized name of the PI that must be searched for

value (required): a text in which instances of the PI are searched for

Output

A JSON document that contains the result(s) of the scan operation

Examples

ledc.ugent.be:8828/scan?property=ledc.ugent.be/identifier%23issn:*&value=This%20is%20my%20number%2001650114
