Portal Use

How

Document -> Agency

To display the agency(ies) that relate to a discovered document - in search results.

All element values which have an encoding scheme of NZGLS-AN represent an agency name, regardless of the element they are contained in.

The link to an agency metadata record is done through a search: where Title=agency name and Type.Category='agency'.

Note: To link directly to an agency's web site (home page) from a document, if there is one, might be possible but might not be easy. A two step process might be best.

Document -> Service

To display the service(s) that relate to a discovered document - in search results

All element values which have an encoding scheme of NZGLS-SN represent a service name, regardless of the element they are contained in.

The link to a service metadata record is done through a search: where Title= service name (from current metadata record) and Type.Category='service'.

Note: To link directly to the service page on the web, if there is one, would be possible but more complicated. A two step process might be best.

Document -> Document

To display other documents that relate to a discovered document - in search results.

This is handled by the current NZGLS Relation element, which would normally contain the URIs of related documents. This is basic AGLS and DC functionality.

Clicking on the URI would take the user directly to the related document, if it was a web address.

Note: Related documents would not necessarily have NZGLS metadata, but if they did and if the Portal wanted to link to it, this would be done with a search: where identifier=URI (from current metadata record).

Service -> Agency

To indicate the agency(ies) that provide a service - in a listing of services or in search results.

Exactly the same as for Document -> Agency above. According to NZGLS, the primary agency will be identified in the Creator element

Service -> Service

To indicate relationships between services - in a listing of services or in search results

Exactly the same as for Document -> Service above.

Service -> Document

This is one of the main search mechanisms in the Portal whereby, once a service is chosen, a search returns all related documents.

The search would include the following criteria: where Relation=service name and Category.Type='document'.

Note: More specificity could be gained by adding 'and encoding scheme=NZGLS-SN' but this is probably not necessary

Agency -> Agency

To indicate relationships between agencies - in an agency listing or in search results.

Exactly the same as for Document -> Agency above

Agency -> Service

To provide a list of services, by agency.

A search is required to identify the service records, with the following criteria: where any element=agency name and encodig scheme='NZGLS-AN' and Type.Category='service'.

Note: More specificity could be gained by limiting the search to the Creator element of the service record.

Agency -> Document

Possibly - to display all the documents relevant to an agency

A search is required to identify documents, with the following criteria: where any element=agency name and encoding scheme = 'NZGLS-AN' and Type.Category='document'.
