Metadata defines the layout and lineage of transactional data and master data in the enterprise. According to Gartner's Guido de Simone, enterprise metadata management (EMM) is designed to link, reconcile, and govern the information in our enterprise.
Because managing metadata effectively is a key to properly integrating, cleansing, protecting, and dealing with changes in data, a straightforward, unifying metadata infrastructure is desirable.
Unlike the metadata in legacy platforms, IRI's data definition file (DDF), mapping task (job) control (.*CL), scripts, data class and rule libraries, and ETL XML (flow) project metadata are all accessible, explicit, portable, and common across all data sources and platforms, including Hadoop.
IRI metadata is exposed in self-documenting text scripts you can modify and run anywhere. It is also supported in the IRI Workbench GUI, built on Eclipse™, where it is modeled in EMF so you can easily:
Create and Acquire
Discover, define, or import and convert metadata
See and change source and column-level attributes by hand or in dialogs
Define, apply, save, modify, and re-use rules that affect data in multiple places at once
Save and Reuse
Local, remote, and third-party data, across platforms, projects, and repositories
Data in integration, migration, reporting, masking, and testing jobs
Track, Audit, and Analyze
Data governance (provenance) and regulatory compliance through forward and reverse lineage, and graphical impact analysis
Standardize and Save
Metadata, master data values and formats, and rules (for mapping, masking, or generation)

It's also now used in IRI NextForm (.ncl data migration), IRI FieldShield (.fcl data masking), and IRI RowGen (.rcl test data generation) job scripts, and in IRI Voracity (.xml ETL) workflows.
You can also easily modify, export, and use this metadata in your application and many third-party data and metadata governance platforms.
erwin Mapping Manager (eMM) and the Meta Integration Model Bridge (MIMB) also support IRI metadata. Their users can easily convert BI, CRM, ETL, and modeling tool metadata into the common metadata format of IRI software. Those using erwin (formerly AnalytiX DS) with Voracity can also leverage state-of-the-art metadata lineage and reference data management tools in the same Eclipse GUI, IRI Workbench.
