gepsio Release Rss Feed

Updated Release: Sep 2012 CTP (Sep 09, 2012)

JeffreyFerguson — Mon, 10 Sep 2012 02:28:22 GMT

What's New

Role Types

Role types found in schemas are now available from within Gepsio. The XbrlSchema class now contains a property called RoleTypes. This property is a collection of objects of a new class called RoleType. Objects of the RoleType class expose any role types defined in the schema.

HTTP-Based Schema Linkbase References

Gepsio now supports HTTP-based schema linkbase references. Previous releases assumed that all schema linkbase references were based on local filesystem paths.

CalculationLink.Linkbase Property

The CalculationLink class contains a new property called Linkbase, which references the LinkbaseDocument object containing the calculation link.

LinkbaseDocument.Schema Property

The LinkbaseDocument class contains a new property called Schema, which references the XbrlSchema class referencing the linkbase document.

SummationConcept.Link Property

The SummationConcept class contains a new property called Link, which references the CalculationLink object containing the summation concept.

Resolved Issues

Work Item 9401: Valid XBRL Doc Failing To Be Loaded

The latest Amazon quarterly XBRL filing passes other validation tests I used, however attempting to Load the doc in Gepsio throws an error. Since it is an Object Ref Not Set to Instance error, it is not entirely clear what caused it although the final line in the stack trace is JeffFerguson.Gepsio.QualifiedName.Equals(Object obj). I attach the filing for your ref. Any ideas on how to get around this?

A bug in the QualifiedName equality testing code failed to detect various null conditions. This has been fixed.

Work Item 7843: The given path's format is not supported

Fixed bug that allowed paths of the form "file:///C:/blah/blah/http://blah/blah.org" to be created in GetFullLinkbasePath when filings that reference remote documents are stored locally. This caused a NotSupportedException to be thrown. Supplied as a patch from Codeplex user matthewschrager.

Work Item 9465: WebException Objects Thrown During XbrlSchema Creation Are Not Wrapped in XbrlException Objects

The XbrlSchema constructor uses an XmlTextReader to read an XBRL schema. If the URI for the XBRL schema to be read is an HTTP-based URI, then the XmlTextReader will use the .NET Web stack to read the schema using HTTP. If something fails during that process, the .NET Web stack will throw a WebException. Thrown WebException objects were not wrapped in an XbrlException object and were consequently thrown back to the client as a WebException object.

To be clear that the issue is an XBRL issue caused by an HTTP failure, the XBRL schema creation code now creates an XbrlException object, stores the caught WebException as an inner exception to the XbrlException, and throws the XbrlException object back up to the client.

Work Item 9571: No Support for Taxonomy Role Types

Role types found in schemas are now available from within the object model. The XbrlSchema class now contains a property called RoleTypes. This property is a collection of objects of a new class called RoleType. Objects of the RoleType class expose any role types defined in the schema.

Updated Release: Nov 2011 CTP (Nov 01, 2011)

JeffreyFerguson — Sun, 17 Jun 2012 14:48:01 GMT

This release passes 191 of the tests in the XBRL-CONF-CR3-2007-03-05 conformance suite (which is 32 more than the 159 tests that passed in the last CTP release). This release builds on the previous CTP release in the following ways:

First Class Support For Items and Tuples. Previous releases of Gepsio used a single class called Fact to represent a fact in an XBRL fragment. Starting with this release, the Fact class is a base class for two derived classes: one called Item and the other called Tuple. The Facts collection available from an XbrlFragment object is a collection of Fact objects, and each Fact in the collection could, in fact, be either an Item object or a Tuple object. This work brings the XBRL concept of tuples in as a first-class citizen of the Gepsio object model.
Complete Support For Essence Aliases. This release of Gepsio passes all of the conformance suite tests relating to the concept of essence aliases.
Better Support For Calculation Arc Validation. Gepsio now has a better validation engine for calculation arcs. This release now includes better handling of context-equals and unit-equals items, items with a nil value, and better support for contributing concept items found in tuples.

Gepsio is also available as a NuGet package named JeffFerguson.Gepsio.

Updated Release: Feb 2011 CTP (Jan 31, 2011)

JeffreyFerguson — Mon, 31 Jan 2011 21:51:38 GMT

Version 2.1.0.4 (Feb 2011 Community Technology Preview) – Jan 31 2011

Functionality Added Since Previous Version

Calculation arcs now read values of "order" attributes as decimals, rather than integers. This brings the code in line with section 3.5.3.9 of the XBRL 2.1 spec.
Homegrown (and incomplete) schema parsing implementation replaced with XmlSchema and XmlSchemaSet classes available in the .NET Framework. Provides for much more complete parsing support for all standard XBRL schema constructs.
Deleted obsolete internal class UriPrefixDictionary.

Breaking Changes

The TpyeName property of an Element is now of type XmlQualifiedName rather than string.
The Type property of a Fact is now of type XmlSchemaType rather than the Gepsio-specific AnyType class.

Passed Conformance Tests

The Feb 2011 CTP passes all of the 89 unit tests passed by the previous CTPs as well as the 70 additional Infer Decimals and Precision unit tests in the XBRL-CONF-CR3-2007-03-05 conformance suite, for a total of 159 passed conformance tests.

Resolved Work Items

Work Item 3828

http://gepsio.codeplex.com/workitem/3828

The type for the value of the "order" attribute of the <calculationArc> element is specified in section 3.5.3.9 of the XBRL 2.1 spec as "decimal". Earlier versions of Gepsio were interpreting these values as integers, which was causing a parsing problem when decimal values were used. This has been fixed; values of the "order" attribute used in calculation arcs are now interpreted as decimal values.

The resolution of this issue has forced a breaking change to earlier versions of Gepsio; in earlier versions, the type of the Order property of the CalculationArc class has changed from "int" to "decimal".

Welcome

Welcome to the Jan 2009 Community Technology Preview (CTP) for Gepsio!

A CTP release provides a “sneak peak” into the future, including key features that are envisioned for Gepsio’s ultimate release. A CTP, by its very nature, is early code and may change by Gepsio’s final release. I invite you to download this release and work with it and your XBRL documents. I welcome all feedback, good and bad. Your feedback is welcome and will be very influential in shaping future releases of Gepsio.
