Yonah never anticipated that when she answered an ad in college to typeset for the student newspaper that it would launch her career in metadata, standards and markup. She has been instrumental in implementing change wherever she works. At HBO, she is focusing on Taxonomy Data Governance, leading efforts to extend terminology consistency while adhering to industry standards.

Previously Yonah was at Pearson Education, where she developed and implemented global metadata standards, working side by side with data architects, markup and workflow specialists, and content creators to come up with flexible solutions to meet today’s educational needs. She was active with multiple standards efforts, including BISG committees as well as contributing to the IDPF's EDUPub markup standard. She was a key contributor to Pearson’s rights metadata standard and system implementation efforts. 

She continues to draw on her data conversion experiences garnered at Data Conversion Laboratories, and her markup and training efforts at HarperCollins Publishers. Yonah managed large scale data conversions of legal and tax law publications and brought them into the digital world using SGML and XML for Thomson/RIA. Prior to that, she was Senior Field Applications Specialist at XyEnterprise where she implemented publishing technology changes to companies including the American Kennel Club, AAA, and IEEE. She received her Masters in Library and Information Science from Rutgers University.
