The added value for a user of an extensive content database are the relations between the content.
Your content is worth much more if you can easily refer to related content.
Users will utilise your system more if you can take them further.
Going through all of your content and documents to link them to other content units or sources takes time, a lot of time. Not to mention the required accuracy.
Content designers and creators are too valuable an asset to waste their time linking and referring.
We at Data Conversion Center have been doing exactly this job for years.
Our people know how it works.
We have done this for Word files in a Documentum CMS, for SGML and XML in other Content Management Systems and databases.
Give your people the time to do what they are good at, leave the rest up to us!
