external applications. Ascential's patented translation and identity technology
— advanced Meta Model embedded within MetaStage and MetaBrokers —
can decompose any tools' capabilities into the metadata equivalent of the
Periodic Table of Elements. As MetaStage fundamentally understands what
each tool requires at the atomic level, it can easily recompose metadata for
any other tool that shares common atoms (or concepts) on demand. Ascential
calls this atomic level representation and commonality technique
. This also enables MetaStage to automatically recognize whether a
metadata asset within the metamodel is, in fact, the same thing.
MetaStage Directory is capable of sourcing, sharing, storing, and reconciling
a comprehensive spectrum of metadata:
a. Business metadata: Business rules, definitions, business domains, terms,
glossaries, algorithms and lineage information using business language
(for business users).
b. Technical metadata: Defines source and target systems, and their table
and fields structures and attributes, derivations and dependencies (for
specific users of Business Intelligence, OLAP, ETL, Data Profiling, and ER
c. Operational metadata: Information about operational application execution
(events) and their frequency, record counts, component-by-component
analysis, and other related granular statistics (for operations,
management, and business users).
d. Project metadata: Documents and audits development efforts, assigns
stewards, and handles change management (for operations, stewards,
tool users, and management).
Since all of the Directory's objects are versioned, a complete chronological
audit trail of events is provided. An administrator can roll back a Directory to a
known point in time, or consolidate it for optimal operational efficiency. As
companies usually span multiple time zones and territories, the entire
MetaStage deliverable is National Language Support (NLS) and Unicode
enabled. Multi-tiered access with roles such as administrator, developer,
subscriber and steward can be configured to ensure that the right metadata is
delivered to the right person, at the right time — either singularly, or
integrated with corporate directories such as LDAP.
