Challenge 1 :
Document management requires various attribute representations
Massive unstructured data is difficult to describe and form structured attributes to improve efficiency of recognition, understanding, searching and utilization.
Challenge 2 :
Unified management of document attributes in business systems
Business system silos bring problems of unified management, search and integration to enterprises. Metadata is in demand to underpin business process.
Challenge 3 :
Access pressure of massive document attributes
Huge amounts of unstructured data and rich business applications increase the access pressure of metadata. Thus, metadata services require higher performance, reliability and scalability.
