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 specific versions of the Technology Core. The version number of the Technology Core used by a skill is displayed next to the skill version number after the skill is published. Each version of a skill can use only one version of the Technology Core, while different versions of a skill can use different versions of the Technology Core. You can see the version of the Technology Core used by a particular version of a skill in the Version column in the Skill Versions dialog box: Technology Core Update New versions of the Technology Core may be introduced in future Vantage releases, bringing new technology features. By default, new skills use the latest Technology Core (currently version 3.0). We generally do not recommend choosing an earlier version unless you have a specific need. For example, all Document skills used within the same 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 (2.4 or 2.0) from the drop-down when creating any new Document skills. It is recommended to update your skills to the latest Technology Core version.

​
Updating the Technology Core

When a new version of the Technology Core becomes available, skills in the tenant can be updated to use this new version. When updating the Technology Core used by a skill, note the following:
  • To update the Technology Core used by a Document skill, Classification skill, or OCR skill, you need to edit, train, and publish that skill.
  • To update the Technology Core used by a Process skill, make sure that all the skills used in the Process skill flow have been updated to the same new version of the Technology Core.
  • The Technology Core of a skill created in Advanced Designer can only be updated in Advanced Designer. For more information, see Upgrading to a new version of the Technology Core.
  • 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 the skill and use its previous version instead. To do this, go to the Skill Catalog, select the skill, and click Discard changes on the toolbar.
If a new version of the Technology Core becomes available for a skill, an arrow icon will appear next to the name and version number of that skill: Technology Core Update You can click this icon and update the skill, after which a new version of the skill will appear in the list. This new version will use the new version of the Technology Core. To update the Technology Core of a skill in the skill settings follow these steps:
  1. Open your skill for editing.
  2. On the Skill Designer page, click the skill settings icon next to the name of the skill. In the dialog box that opens, select a Technology Core version from the drop-down list. Technology Core Skill Settings
  3. Save, train, and publish the skill.
The updated skill using the new Technology Core version will appear in the list.

​
Reverting to a previous version of the Technology Core

To revert a skill to an earlier Technology Core version, you can:
  • Open the earlier version of the skill, republish it, and restore its associated Technology Core version (note that the skill’s version number will be updated), or
  • Delete the current version of the skill, which automatically reverts the skill to the previous version that uses the earlier Technology Core.

Importing Technology Core versions

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