The advanced search provides two main functions, each of which are described in more detail below:
- Retrieval service: based on valid database resource names
- Validation service: checks and validates prefix:identifier combination
This service can be used to determine whether a particular data collection is registered in the Identifiers.org registry. The autocomplete feature presents the user with the options that match the input text, based upon the resource name or alternative registered synonyms. Selection of an option displayed in the drop down list will redirect the user to the entry for that data collection in the Identifiers.org registry.
This service allows the user to validate a prefixed identifier, where the prefix can be either a namespace prefix (as listed in the registry, under 'namespace'), or a provider prefix, which identifiers a specific data provider (not currently displayed in the registry). Once a combination is entered, the 'Validate' button will use the Identifiers.org resolving function to retrieve the appropriate information from the Identifiers.org registry, and execute the query. If the data record is retrievable, a link will be displayed below the 'Validate' button. If the query fails, an informative message will detail whether the failure was due to the prefix or identifier components of the text that was inserted in the query box.
