Just as a word processor helps you write a single document;; document management systems help you organize multiple documents. In the same light, you will need some simple tools and processes to manage the data elements in your corporate ontology as they grow from a single OWL file to a family of files that must be consistent. Doing so allows you to:

Track document history Track versioning Search for data Create reports of what documents were created by what individuals View timelines of when groups of data were created

...in large organizations, shared meaning only comes through shared trust. If people do not trust the processes behind your ontology they will not use it and they will tend to re-invent the structures.
