Product Architecture Overview

PCC WOPI Client is an IIS web application that supports SharePoint integration via the MS-WOPI protocol. This component provides an interface between SharePoint and PCC or ACS imaging services. This enables the following capabilities with SharePoint: document viewing, interactive preview, viewer permissions, and document conversion.

The PCC for SharePoint architecture leverages native SharePoint permissions when accessing documents. For example, if a user or group has 'View Only' permission, they will be unable to download a document from SharePoint. If a user or group has permission to 'Edit Items', e.g., 'Contribute' permission level, then user will also be able to edit and download.

In addition to native SharePoint permissions, PCC for SharePoint provides custom permissions to restrict viewer features. Site and library admins use native SharePoint administration interfaces to grant viewer permissions to users and groups.

PCC for SharePoint can be configured to view Office documents in the PCC viewer, and edit in Office Web Apps, or configured to view and edit in Office Web apps, and only view non-Microsoft formats in the PCC viewer.

Prizm Content Connect or Accusoft Cloud Services Viewer

The PCC-WOPI Client allows you to integrate SharePoint with an installed, on-premise viewer (PCC) or a cloud-based viewer (ACS):

Prizm Content Connect (PCC) is a standalone, on-premise product that exposes a set of web services (Prizm Content Connect Imaging Services or PCCIS). Prizm Content Connect must be installed within your organization in addition to the PCC for SharePoint installation.
Accusoft Cloud Services (ACS) is a suite of cloud-based APIs that provide your applications access to advanced document viewing, image compression, document conversion, and more.
