Short nameNUMHUS
Description

This field complements the HUSID field to identify the separate courses that individuals take. HUSID + Institution identifier + NUMHUS together form a unique identifier known as HIN. An identification of the basic unit of 'a coherent engagement with the institution aiming towards the award of a qualification(s) or credit'.

Notes

This is identical to the Instance.NUMHUS field in the Student record.

Field length 20 is to allow institutions to use an instance identifier already held internally. Where a instance identifier held internally is used, institutions must continue to use this number even when transfers or natural progressions occur. As a consequence of this institutions may find it easier to number student instances sequentially starting from 1 or A etc. A new instance number format can only be introduced for instances that have not been returned to HESA. This will be the case for new entrants and for continuing students commencing courses that have not previously been returned to HESA.

Valid characters

The valid characterset available for this field follows the Data Standards in the HESA record.

  • The general policy is to support all Latin-based characters for names, addresses and general text fields, but not non-Latin characters.
  • All Unicode code charts for Latin characters are supported. These are Basic Latin (excluding the C0 control characters), Latin-1 (excluding the C1 control characters), Latin Extended A, Latin Extended B and Latin Extended Additional. This set corresponds to Unicode code points U+0020 to U+007F and U+00A0 to U+024F.
  • Schemas are built in such a way that an individual project can further restrict the set if required.

The character set chosen will support Welsh and Gaelic languages as well as all European and most other languages using a Latin-based character set.

The Unicode charts that list each of the characters in this range can be found on the Unicode web site. The specific sets that are defined here are shown in the following PDF documents:

Files must be encoded with UTF-8 and schema validation will be in place to ensure this. Institutions must specify the encoding used in their XML files in the first line of the file (i.e. <?xml version="1.0" encoding="UTF-8" ?>) and to ensure that their files are actually saved with that encoding. If XML files are edited with some text editors and the encoding is not specified or does not match the actual file encoding, there may be problems when submitting these files for validation.

Reason required

To distinguish - and between years, link - episodes of study by the same student at the same institution; a vital tool (through the generation of HIN) to support year-on-year linkage.
