11.20.10 Instance — Contexts

After a load has been performed, the contexts are sorted by ID for fast searching.

The following key name are use as context list entries or as table columns:

Key Name		Description/Comment

Control Information:
	position†	A decimal string specifying the position of the item within the context records. This can be used for direct access to data records.
	id	String context ID as specified by the instance. This value must be unique and the context list primary sorted key is based on this ID.
Basic Data:
	entity†	The legal entity axis.
	scheme†	The legal entity scheme (unique URL for type and syntax).
	date_a	The instance date or the starting date of a duration.
	date_b	The ending date of a duration.
Dimensions:
	dimension_xx	Zero or more dimension concepts. If not present, this key is not used.
	domain_xx	Zero or more typed concepts. If not present, this key is not used. This field is only used with typed members.
	value_xx	Zero or more member concepts or data values. If not present, this key is not used.
	member_flags_xx	Flags for the member entry such as errors, type, etc.
Position: †
	c_sy c_sx	Open tag group file position.
	c_ey c_ex	Close tag group file position.
	order	A decimal string specifying the order of the item as originally read from the source.
Instance Stats:
	ref_cnt†	Number of fact references.
	ct_flags	A hexadecimal version of flags associated with the entry.

† This value is not presented in terse mode.

Sequential dimensional key numbers start at “01” to the maximum number of keys. The key name will not be in the list if the underlying value is not present in the context. The key name position will always be in order. As such, if an axis is located in a list or column, the +2 index will be the value.

Typed members and explicit members share the same data space using the above sets of named and numbered keys.

For Typed Members, the fields are as follows:

dimension The type axis concept name, normally with an “Axis” suffix.

domain The type domain concept name, normally with an “Domain” suffix.

value The type axis value or data as string data or a concept name.

Explicit Members will not have the domain field present (no key name) in the result:

dimension The dimension concept name, normally with an “Axis” suffix.

value The member concept name, normally with an “Member” suffix.

The key names relate as follow to XML XBRL. For Typed Members:

<xbrldi:typedMember dimension="dimension">
<domain>value</domain>
</xbrldi:typedMember>

For Explicit Members:

<xbrldi:explicitMember dimension="dimension">value</explicitMember>

The relationships are not validated against the taxonomy or other linkbases.

To access the flags, the HexToInteger function can be used. The context entry and member entries have the following bitwise flags:

Definition		Bitwise	Description
Context Flags (ct_flags)
Errors
	XM_CONTEXT_ERROR_MASK	0x0000FFFF	Mask for Error Bits
	XM_CONTEXT_DUPLICATE_ID	0x00000001	Duplicate ID
	XM_CONTEXT_DUPLICATE_CONTENT	0x00000002	Duplicate Content
	XM_CONTEXT_MISSING_CONTENT	0x00000004	Missing Content
	XM_CONTEXT_NOT_REFERENCED	0x00000008	Not Referenced
	XM_CONTEXT_PROPERTY_ERROR	0x00000010	Error in Property

Member Data Flags (md_flags)
Conditions
	XM_MEMBER_EXPLICIT	0x01	Explicit Dimension
	XM_MEMBER_TYPED	0x02	Typed Dimension
	XM_MEMBER_ERROR	0x80	Dimension has an Error
