Re: 'Formats in present':                        

'danMARC' format provides records in standard 'danMARC2' format in compliance with ISO-2709.

The danMARC2 format supports two methods of multivolume registration; all descriptive data in one record as in the MARC21 format or as records of two or more levels.

The principles for multilevel records are that descriptive data covering all volumes are registered in the top level record ("hovedpost") and the descriptive data specific to the volume are registered in the bottom level record ("bindpost").
A middle level record ("sektionspost") may occur if the work includes sections.

The records are linked from the bottom up by record id to the upper level record in the danMARC2 field 014 subfield a.

Within the format OID (1.2.840.10003.5.14) for danMARC the following present formats are offered as element set names used for the Danish hierarchical record structure:

  • hoved - provides the top level record
  • sektion - provides the middle level record
  • bind - provides the bottom level record or the one level record

XML is offered for danMARC2 as the MarcXchange format. It is called using format OID: 1.2.840.10003.5.109.10 and the default "present" format of this OID is the element set name danmarxchange. 

The marc21 format OID: 1.2.840.10003.5.10 provides records in standard MARC21 format as ISO-2709. It is possible to present records in MARC21 with special adjustments for the Danish Royal Library via element set name 'kb'.

Re: 'Search syntax':

Within attribute set BIB-1 (OID: 1.2.840.10003.3.1) the following "use" attributes are supported: 

  • 4 (title)
