The Technology Core is a set of technology-related workers for document processing, OCR, classification, data extraction, and other features. All skills in Vantage use a specific version of the Technology Core. You can find the Technology Core version used by a particular skill version in the Version column in the Skill Versions dialog box:
Skill Versions dialog box showing the Technology Core version for each skill version
Each version of a skill uses one version of the Technology Core. Different versions of the same skill can use different Technology Core versions.
We recommend using the latest Technology Core version (currently 3.0) for all skills unless you have a specific need for an earlier version.
All Document skills used in a Process skill must use the same Technology Core version. If your Process skill already includes Document skills built on Technology Core 2.4 or 2.0, select the corresponding version from the drop-down when creating any new Document skills.
New versions of the Technology Core may be introduced in future Vantage releases, bringing new technology features.

​

When a new version of the Technology Core becomes available, an arrow icon appears next to the name and version number of the skill:

Save, train, and publish

Save, train, and publish the skill. The updated skill appears in the list, using the new Technology Core version.
Before publishing a skill with an updated Technology Core, check its extraction statistics. If the new version performs worse than the previous version, you may prefer not to publish. To revert, go to the Skill Catalog, select the skill, and click Discard changes on the toolbar.

​
Revert to a previous version of the Technology Core

To revert a skill to an earlier Technology Core version, you have two options:
  • Republish an earlier version: Open the earlier version of the skill and republish it to restore its associated Technology Core version. Note that the skill’s version number will be updated.
  • Delete the current version: Delete the current version of the skill, which automatically reverts to the previous version that uses the earlier Technology Core.

​
Import Technology Core versions

Skills imported with an unsupported Technology Core version must be retrained and republished to be usable.
