Only one

Gloss
PreSpace false t description

record with the same id field will be current at any point in time. The current record will be the one with the most recent

Specref
RefType (field) t effectiveTime

before or equal to the point in time under consideration.

If the

Gloss
PreSpace false t active

field of this record is false ('0'), then the

Gloss
PreSpace false t description

is

Gloss
PreSpace false t inactive

at that point in time. If the

Gloss
PreSpace false t active

field is true ('1'), then the

Gloss
PreSpace false t description

is associated with the

Gloss
PreSpace false t concept

identified by the conceptId field.

The conceptId field, the languageCode field and the

Specref
RefType (field) t typeId

field will not change between two rows with the same id, in other words they are immutable. Where a change is required to one of these fields, then the component will be inactivated (by appending a row with the same id and the

Gloss
PreSpace false t active

field set to false) and a another row will be added representing a new component with a new id. Only limited changes may be made to the term field, as defined by editorial rules.

Each

Gloss
PreSpace false t concept

will have at least one

Gloss
PreSpace false t active description

with a

Specref
RefType (field) t typeId

of

Concept
t 900000000000013009|synonym| ShowFormat inline

and at least one

Gloss
PreSpace false t active description

with a 

Specref
RefType (field) t typeId

 of

Concept
t 900000000000003001 |Fully specified name|

.

Where a

Gloss
PreSpace false t concept

only has one

Gloss
PreSpace false t active description

with a

Specref
RefType (field) t typeId

of

Concept
t 900000000000003001 |Fully specified name| ShowFormat inline

across all

Gloss
PreSpace false t language

codes within a release, then that

Gloss
PreSpace false t Description

can be taken as the

Gloss
PreSpace false t Fully Specified Name

for all

Gloss
PreSpace false t languages

and

Gloss
PreSpace false t dialects,

and need not be explicitly included in every

Gloss
PreSpace false t language

Gloss
PreSpace false t reference set

associated with that release.

The

Specref
RefType (field) t term

field will be restricted as follows:

• to an overall maximum length of 32Kb;

• to a maximum length, configurable for each

  Gloss
  PreSpace false t description type

  as defined in the

  Concept
  t 900000000000538005 |Description format reference set| ShowFormat inline

  member associated with that

  Gloss
  PreSpace false t description type

  - see the  Description Format Reference Set specifications document for more details.

• The

  Concept
  t 900000000000538005 |Description format reference set| ShowFormat inline

  also defined the format of the term field (plain text, limited HTML, XHTML) for each

  Gloss
  PreSpace false t description type.

• Control characters (including TABs, CRs and LFs) will not appear in

  Concept
