Enterprise Semantic and MetaData Management At Work

Xtensible Client Journey

Xtensible has been working with this client for over 15 years and we are still supporting them in creating the 21st century power network for 15 million customers covering 50,000 square miles. Today their enterprise analytics platform generates 10 terabytes of data weekly.

Changes to the electric grid are necessary and will continue to be needed based on technology advancements and consumer expectations related to reliability and affordability as well as the growing global awareness of environmental impacts. Data model governance is a key factor in long-term success and sets the stage for future expansion and growth, an area where we have considerable expertise.

During this journey we utilized MD3i for semantic modeling, the beginnings of Affirma. Affirma is now a single solution for enterprise semantic modeling and metadata management.


Who we are

Xtensible Solutions first opened its doors in 1998 as a standards-based consulting company for the utility industry. Since the company’s early days, when three friends hunched over a wobbly table in an unfinished basement to finalize Xtensible’s original MDi framework, Xtensible has enjoyed a culture that values leadership, innovation, and community.
