Features and Status

May 31, 2012

open source xbrl platform

Why?

Response to XSB survey for open sourceFoster wider XBRL adoptionEasy-to-learn, compact implementationSupport for XBRL versioning, formulaFully integrated test suite, RSS feedsPlug-in extension architecture

What?

XBRL can be loaded, viewed, validated

Instances, DTSes, Version reports, RSS feedsDTS comparisonsFormula checks

Users can interact directlyDesktop GUI, Command line, Web Services

Programmers can use featuresAPI and plug-in access to all features

User-developed suitesUsers can run standard suitesGUI and Batch operation

Plug-in validation extensions

Integrated Test Suite View

Versioning

Produce versioning reportsLoad two DTSesDiff produces versioning report

Consume versioning reportsValidates to CR specifications

Formula linkbase

Formula instance output & assertionsLoad formulas, validate

Debug traces and stepsFull conformant implementationOptimization

Integrated RSS Feed Watching

RSS feed object model integrationWatch criteria (e-mail alerts)

Text (regex) matchFormula assertion

Motivate XBRL Formula UseUser formulas to watch filings(Better use of your PC than SETI?)

RSS Feed Control

RSS Feed View

Text matched!

MVC Architecture

ModelDocuments, DTS objects, Vers. objectsFormula objects

API

Examples providedValidation (Vers. and Filer manuals)Tree walks (Linkbase and XDT)DTS, formula objects

Community helps evolve APISimplicity of {use, implementation}Easy to integrate {external use of API}Future transition to AMTF-based API

Performance - Optimization

At presentFocus is open-source of featuresMemory twice of commercial productsDimensional optimizationFormula optimizations
