Design

  • Gepsio now supports the automatic loading of industry standard schemas. See this blog post for more information.
  • If Gepsio attempts to load a schema from an HTTP-based schema reference, but cannot find a schema at the specified URL, then Gepsio will attempt to load the schema from the same local folder containing the XBRL fragment that referenced the schema. This allows XBRL instances based on Dutch taxonomies to be loaded, for example, since HTTP-based schema references to those taxonomies are only placeholders. XBRL documents containing references such as <lnk:schemaRef xlink:href="http://archprod.service.eogs.dk/taxonomy/20171001/entryDanishGAAPBalanceSheetAccountFormIncomeStatementByNatureIncludingManagementsReviewStatisticsAndTax20171001.xsd" xlink:type="simple"/> could not be loaded by earlier versions of Gepsio, since the specified schema reference URL is actually invalid. With this version, upon discovering the load failure in that schema reference example, Gepsio will attempt to load entryDanishGAAPBalanceSheetAccountFormIncomeStatementByNatureIncludingManagementsReviewStatisticsAndTax20171001.xsd from a local folder.
  • The XbrlSchemaCollection class now implements IEnumerable<XbrlSchema>and, as such, can be used in iteration expressions such as foreach.

Breaking Changes

  • In the previous release, the XbrlSchema class maintained a string property called Path, which maintained the path to a loaded XBRL schema file. This property has been removed and has been replaced with two new string properties: SchemaReferencePath, which specifies the schema's path as specified by the XBRL fragment's <schemaRef> elmement, and LoadPath, which specifies the path to the schema file as Gepsio actually loaded it. These two paths will, under ordinary circumstances, be the same, but may differ if Gepsio encounters an HTTP 404 while trying to load an HTTP-based schema reference and needs to load the schema from a local folder.

Conformance

  • Attribute values on facts are now checked to ensure that they are convertible to the attribute's defined data type (see conformance test XBRL-CONF-CR5-2012-01-24 314-lax-validation-04.xml).
  • More conformant handling of negative fact values used in calculation arc validations.

Conformance Tests In XBRL-CONF-2014-12-10 Passed by Gepsio

Tests marked NEW failed in previous releases but now pass due to Gepsio's increased conformance with the XBRL 2.1 Specification.

Identifier Scope [Section 4.3 The Item Element]

  • 301-01-IdScopeValid.xml [301.01 Valid example of id attribute.]
  • 301-03-IdScopePeriodDiff.xml [301.03 Mismatch of periodType attribute and referenced context's period type.]
  • 301-04-IdScopeContextRefToUnit.xml [301.04 contextRef has IDREF to unit element.]
  • 301-05-IdScopeUnitRefToContext.xml [301.05 unitRef has IDREF to context element.]
  • 301-06-FootnoteScopeValid.xml [301.06 Valid example of footnote link href attribute.]
  • 301-08-FootnoteToContext.xml [301.08 href attribute is referencing to context element.]
  • 301-09-FootnoteToUnit.xml [301.09 href attribute is referencing to unit element.]
  • 301-10-FootnoteFromOutOfScope.xml [301.10 The instance contains two footnote links. The second one contains an arc with a from value that does not have a corresponding loc in the same extended link.]
  • 301-11-FootnoteToOutOfScope.xml [301.11 The instance contains two footnote links. The second one contains an arc with a to value that does not have a corresponding footnote resource in the same extended link.]
  • 301-12-FootnoteLocOutOfScope.xml [301.12 The instance contains a footnote link. In the footnote link there is a loc element that has an href that points to a fact in another instance document.]
  • 301-13-FootnoteLocInScope.xml [301.13 The instance contains a footnote link. In the footnote link there is a loc element that has an href that points to a fact in the instance document using the instance document file name with a fragment identifier.]
  • 301-14-FootnoteFromResource.xml [301.14 The instance contains a footnote link. The arc in the footnote link has a from value that matches a footnote resource. This is not valid for the fact-footnote arc role on the arc. The from must point to a loc which in turns points to a fact in the same instance document.]
  • 301-15-FootnoteToLoc.xml [301.15 The instance contains a footnote link. The arc in the footnote link has a from value that matches a footnote resource. This is not valid for the fact-footnote arc role on the arc. The from must point to a loc which in turns points to a fact in the same instance document.]
  • 301-16-FootnoteWithoutLang.xml [301.16 The xml:lang attribute is missing on the footnote resource.]
  • 301-17-FootnoteCustomArcRole.xml [301.17 The footnote custom arc role can relate two footnotes to each other instead of just fact to footnote. (Only the standard footnote arc role is restricted to being from item or tuple locators.) Maybe this might be used to indicate how some footnote is "footnoting" another footnote.]

Unit of Measure Consistency [Section 4.4 The Context Element]

  • 304-01-monetaryItemTypeUnitsRestrictions.xml [304.01 An element with a monetary item type has an ISO currency code for its units (using the standard ISO namespace prefix).]
  • 304-02-monetaryItemTypeUnitsRestrictions.xml [304.02 An element with a monetary item type has an ISO currency code for its units (using a non-standard ISO namespace prefix).]

  • 304-04-monetaryItemTypeUnitsRestrictions.xml [304.04 An element with a type derived by restriction from monetary item type has an ISO currency code for its units (using a non-standard ISO namespace prefix).]
  • 304-05-monetaryItemTypeUnitsRestrictions.xml [304.05 An element with a non-monetary item type has an ISO currency code for its units (using the standard ISO namespace prefix).]
  • 304-06-monetaryItemTypeUnitsRestrictions.xml [304.06 An element with a monetary item type does not have an ISO currency code for its units - the namespace is wrong.]

  • 304-09-monetaryItemTypeUnitsRestrictions.xml [304.09 An element with a type derived by restriction from monetaryItemType does not have an ISO currency code for its units - the local name is wrong.]
  • 304-10-pureItemTypeUnitsRestrictions.xml [304.10 An item with a pureItemType data type MUST have a unit element and the local part of the measure MUST be "pure" with a namespace prefix that resolves to a namespace of "http://www.xbrl.org/2003/instance".]
  • 304-11-pureItemTypeUnitsRestrictions.xml [A measure element with a namespace prefix that resolves to the "http://www.xbrl.org/2003/instance" namespace MUST have a local part of either "pure" or "shares". The value 'impure' is not a valid measure in the XBRL instance namespace.]
  • 304-12-pureItemTypeUnitsRestrictions.xml [Unlike for monetaryItemType and sharesItemType, there is no constraint (in 4.8.2 or elsewhere) requiring an item with a pureItemType data type to have a particular kind of unit.]
  • 304-12a-pureItemTypeUnitsRestrictions.xml [Same as V-12, but the pure measure has no prefix and the default namespace is undefined.]
  • 304-13-sharesItemTypeUnitsRestrictions.xml [304.13 For facts that are of the sharesItemType, units MUST have A single measure element. The local part of the measure MUST be "shares" and the namespace prefix that MUST resolve to http://www.xbrl.org/2003/instance]
  • 304-14-sharesItemTypeUnitsRestrictions.xml [304.14 For facts that are DERIVED BY RESTRICTION from the sharesItemType, units MUST have A single measure element. The local part of the measure MUST be "shares" and the namespace prefix that MUST resolve to http://www.xbrl.org/2003/instance]
  • 304-15-pureItemTypeUnitsRestrictions.xml [304.15 For facts that are of shares item type, units MUST have A single measure element. The local part of the measure MUST be "shares" and the namespace prefix that MUST resolve to http://www.xbrl.org/2003/instance. In this case the unit has two measure elements, both of which are pure.]
  • 304-15a-sharesItemTypeUnitsRestrictions.xml [Same as V-15 but in this case the unit has has shares but no prefix and the default namespace is undefined.]
  • 304-16-unitsInSimplestForm.xml [304.16 The units must not have numerator and denominator measures that cancel.]
  • 304-17-sameOrderMeasuresValid.xml [304.17 The units equality test which two units have same order measures.]
  • 304-18-sameOrderDivisionMeasuresValid.xml [304.18 The units equality test which two units have same order divisions.]
  • 304-19-differentOrderMeasuresValid.xml [304.19 The units equality test which two units have different order measures.]
  • 304-20-differentOrderDivisionMeasuresValid.xml [304.20 The units equality test which two units have division elements which their order of child measures are different.]
  • 304-21-measuresInvalid.xml [304.21 it tries to essence-alias equality of two elements with different units : where one is pure-feet and the second is pure-pounds. so the alias essence check is invalid and it should throw an error in xbrl validation]
  • 304-22-divisionMeasuresInvalid.xml [304.22 The test tried to essense-alias equality check of two elements with different units : where one is unit between "pure-inch / pound-feet" and other "pure-feet / pound-inch". The tests is invalid as it should throw an error during xbrl validation.]
  • 304-23-Calculation-item-does-not-match-unit.xml [Variation of 304-15 where the type of the fact value does not match that of the type of the reported element. Shares type versus Monetary unit]
  • 304-24-valid-ISO-unit-of-measue.xml [Valid ISO unit of measurement example]
  • 304-25-measure-reported-with-prefix-undefined-instance.xbrl [Measure reported with prefix undefined is considered XBRL invalid]
  • 304-26-monetaryItemTypeUnitsRestrictions.xml [Monetary item reported with unit having a denominator.]

Decimal and Precision Mutual Exclusion and prohibition on nil items [Section 4.4 Items]

  • 305-01-DecimalOnlySpecified.xml [305.01 item has only Decimals specified]
  • 305-02-PrecisionOnlySpecified.xml [305.02 item has only Precision specified]

  • 305_07_invalid_instance.xbrl [305.07 a genuine inconsistency due to roll up of child values]
  • 305-08-UnitsSpecifiedOnNilItem.xml [305.08 nil items have no decimals or precision, with unitref, but the type specifies fixed values for decimals and precision.]

Required Arc in Definition Linkbase [Section 5.5.6.4.1.5]

  • 306-01-RequiredInstanceValid.xml [306.01 The instance contains two elements in the same context. The presence of one element forces the presence of the other.]
  • 306-02-RequiredInstanceTupleValid.xml [306.02 The instance contains an item and a tuple. The presence of the tuple forces the presence of the item.]
  • 306-03-RequiredInstanceInvalid.xml [306.03 The instance contains an item and a tuple. The presence of the tuple forces the presence of the item.]

Schema References [Section 5 Taxonomies]

  • 307-01-SchemaRefExample.xml [307.01 A schemaRef element MUST hold the URI of a schema. In this case it does.]
  • 307-02-SchemaRefCounterExample.xml [307.01 A schemaRef element MUST hold the URI of a schema. In this case it does not because the second reference to a schema actually points to an XML document that is a label linkbase. ]
  • 307-03-SchemaRefXMLBase.xml [307.03 schemaRef elements MUST hold the URI of Schemas. In this case the requirement is not satisfied because the schema reference has to be resolved using the XML base attribute that ensures the schemaRef URI resolves to the XML document in the base directory. This document, however, is a label linkbase, not a schema. If the XML base attribute value is not used then the schema in the same directory as the instance is discovered and no issues are noticed.]

Duplicate instance roleRef and duplicate arcroleRefs [3.5.2.4.5 and 3.5.2.5.5 duplicate instance roleRef and arcroleRef elements.]

  • 308-01-instance.xml [Instance contains two role references to the same URI, INVALID]

LAX validation tests [Test that LAX validation is performed]

  • 314-lax-validation-01.xml [Segment has an element for which there is no definition, so it is allowed; item has an attribute with no definition, so it is allowed. The definitions are imported to the discovered taxonomy.]
  • 314-lax-validation-02.xml [Segment has an element for which there is no definition, so it is allowed; item has an attribute with no definition, so it is allowed. The definitions are found by schemaLocation from the instance document.]

  • 314-lax-validation-04.xml [Same as v-01 but item has an attribute defined as integer with string contents]
  • 314-lax-validation-05.xml [Same as v-02 but segment has an element defined as integer with string contents]
  • 314-lax-validation-06.xml [Same as v-02 but item has an attribute defined as integer with string contents]

  • 320-21-BindCalculationInferPrecision-instance.xbrl [320.21 - Duplicate Facts reported and thus calculation will not bind per 5.2.5.2; Test ensures that we do not bind the calculation due to a duplicated fact and do not infer precision.]
  • 320-22-BindCalculationInferPrecision-instance.xbrl [320.22 - Duplicate Facts reported and thus calculation will not bind per 5.2.5.2; Test ensures that we Do NOT bind the calculation and do not infer precision. If it did bind then there would be an inconsistency.]

  • 320-25-BindCalculationInferPrecision-instance.xbrl [320-25 - Invalid; Test: Verifies that IsNill facts do not bind to calculations per 5.2.5.2]
  • 320-26-BindCalculationInferPrecision-instance.xbrl [320-26 - Valid, but contains number likely to sneak in errors in floating point multiplication of the weight 0.45 x A113 (=1010103). For non-decimal CPU arithmetic rounding may be required on each weight multiplication to avoid floating point weirdnesses. (this irritation contributed by Herm Fischer)]
  • 320-30-BindCalculationInferDecimals-instance.xbrl [Tests that a decimals 0 value 0 is not treated as precision 0 (invalid) but as numeric zero. In the prior approach where decimals 0 value 0 converted to precision 0 value 0, this would have been invalid.]
  • 320-31-BindCalculationInferDecimals-instance.xbrl [Edge case tests that decimal rounding with is performed. In decimals representations, summation 0d1 is compared to contributing items 1.234d2 and -1.223d2. Contributing items round to 1.23 and -1.22, the contributing items rounded sum is .01. Summation has decimals 1 which is applied to comparing 0 decimals 1 to contributing items rounded sum .01, but in decimals 1, which makes the contributing rounded sum .01 be rounded as .0, which is equal to summation zero decimals 1, in decimals. If the calculation were performed the old way, treating summation 0d1 as 0p0 this alone would make the calculation roll up be invalid. But many processors have anyway treated 0d1 as 0p1, in which case such a processor still would be comparing numeric 0 for the summation, to the rounded contributing items sum .01 in some non-zero precision, which would still be invalid. So the point of this test is to be sure the processor is using the all-decimals calculation roll up.]
  • 320-32-BindCalculationInferDecimals-instance.xbrl [Checks that .5 rounds half to nearest even]
  • 320-33-BindCalculationInferDecimals-instance.xbrl [Checks that .5 rounds half to nearest even regardless]
  • 320-34-BindCalculationInferDecimals-instance.xbrl [Checks that .5 rounds half to nearest even regardless whether a processor uses float]
  • 320-35-BindCalculationInferDecimals-instance.xbrl [Same as V-34 but sum is 2.9 so if rounding were in float, the floating inprecision would make the 'bad' rounding look correct, whereas if rounding were in decimal, it would be invalid.]

Internationalization of xlink:href content [Test the implementation of converting the xlink:href from the represented character string into the right URL for file names and the content of ID attributes]

  • 321-01-internationalization-instance-invalid.xml [321-01 the instance document refers to a taxonomy that contains item definitions using Spanish characters.

s-equal tests [Test equvalent relationships processing]

  • NEW 331-equivalentRelationships-instance-01.xml [t:P1 is a summation of t:P2 and t:P3. The contributing items have a calculation inconsistency. Following tests will use relationship equivalence to prohibit (or not be successful at prohibiting) P3 so the sum is clean (or inconsistent if unsuccessful at prohibiting), and thus the test case determines if equivalency matches the spec (by prohibition successfulness in subsequent tests).]
