Uploading Tenant Code to a Multi-Tenant System

A computer-implemented method for uploading tenant code to a multi-tenant system to share document data, comprising:

• receiving a metadata definition language (“MDL”) representation of tenant code from a computing device over a network;
• storing the tenant code as source code metadata in a first repository of the multi-tenant system;
• registering the tenant code with a tenant code registry of the multi-tenant system;
• receiving a request for the tenant code from a server of the multi-tenant system when there is a predetermined event;
• extracting the tenant code from the source code metadata for execution;
• executing the tenant code to create, in a second repository of the multi-tenant system, a temporary copy of a source document in the first repository of the multi-tenant system, with information of the source document transferred from the first repository of the multi-tenant system to the second repository;
• and
• displaying the temporary copy of the source document before copying the source document from the first repository to the second repository.
