With over two decades of active experience as a technical architect, Timothy Valihora provides a broad range of skills in the information technology space. One of Timothy Valihora’s areas of expertise is in the utilization of the IBM Information Governance Catalog (IGC). IGC was introduced at IBM InfoSphere Information Server (IIS) v11.1 and is essentially a re-worked offering of “Business Glossary” and the former “MetaData Workbench” products.
IGC offers organizations a means of managing and comprehending their information. It enables companies of any size to store and manage their valuable data assets in a centralized system created for the purpose.
The key components of IGC include Business Glossary (used to define a corporate ‘vocabulary’ of categories, terms, policies and rules) and Information Assets (technical objects generally loaded via IBM MetaData Asset Manager – or IMAM) which can then be mapped to terms within Business Glossary.
Tim Valihora has extensive experience in assisting companies to utilize IGC to i) define their business and technical metadata in the glossary, ii) establish data governance policies which can be achieved through establishing and enforcing rules, iii) establishing responsibility (ownership) of information assets through stewardship – and iv) linking business metadata to technical metadata.
In addition Mr. Valihora is an expert at “Open IGC” which involves creation of a custom asset bundle within IGC (these assets are generally objects that a company would like to define but are not able to come into the governance catalog via one of the available connectors within IMAM.)
Open IGC relies upon calling the IGC Rest API for both querying and creating new custom content. Ideally DataStage jobs are used for this purpose and Tim Valihora has extensive experience writing such programs which utilize the Hierarchical Data stage – that includes REST functionality which is idea for both JSON and XLM calls to the REST API.
Using the Glossary Development component – governance policies, rules, categories, terms, labels, and the inclusive data hierarchy setup are established and can be manually customized via custom attributes. In addition, the import wizard of the Information Governance Catalog allows for the uncomplicated import of existing categories, labels, governance, and rules.
Those who have access to the catalog are users who have designated security and workflow roles. Access based on specified roles guarantees that only authorized users can access, create, and manipulate data assets assigned to them.
