About the SharePoint Online Add-In

The SharePoint Add-in enables your SharePoint application to interact with the AutoClassifier Engine to enable tagging in SharePoint document libraries and lists.

The SharePoint Add-in is comprised of four key components:

1. SharePoint Add-In Apps:
   1. These Apps resides in your SharePoint App Catalog.
      
2. IIS website:
   1. This website can reside on any Microsoft IIS Server which is exposed to network access from the SharePoint site.  
   2. If you are installing the AutoClassifier Engine website and the Add-in website on two different Microsoft IIS Servers, there must be network access between the servers.
      
3. Windows Service for synchronizing the SharePoint Term Store with the AutoClassifier Engine.
   
4. Windows Service for running Scheduled Annotation Jobs in SharePoint.

AutoClassifier for SharePoint Online/2013/16/19/SPSE Add-In can work in one of the two modes described below.

Before you continue with your installation decide which mode better fits your requirements. 

• Regular Mode
  • AutoClassifier pushes metadata values in SharePoint Online/2013/16/19/SPSE lists and libraries if these contain columns with names that match the AutoClassifier output metadata names.
    
    • Example:
      1. If AutoClassifier outputs the metadata "DetectedLanguage"
         
      2. And the SharePoint List or Library contains a column named "DetectedLanguage"
      3. Then during the annotation process, that column is populated with the value of the detected language
         
• Search Tags Mode
  • AutoClassifier automatically creates columns to match the metadata processed by AutoClassifier Processing Pipeline in SharePoint Lists or Libraries.
  • No manual creation of columns
  • Columns are created automatically
