System and method of document embedding in collaborative editors

A non-transitory computer readable medium storing computer program instructions, which, when executed on a processor, cause the processor to perform a method comprising:

• embedding, by a device, in a first frame, a second frame;
• receiving, a request from the second frame to establish communication with the first frame, wherein the request includes a domain of a third party application that is part of the second frame;
• verifying, the domain of the third party application part of the second frame to be from a list of allowed origins;
• establishing, communication between the first frame and the second frame based on the verifying;
• generating a first mutation defining a first change made to a document within the first frame, the first mutation assigned a first embed identifier associated with the first frame, and a second mutation defining a second change made to the document within the second frame, the second mutation assigned a second embed identifier associated with the second frame;
• receiving at the first frame, the second mutation and the second embed identifier, wherein the first frame verifies the second mutation being from the third party application of allowed origins;
• transmitting the first mutation and the first embed identifier and the second mutation and the second embed identifier to a remote server;
• receiving, from the remote server, a first instruction relating to the document and comprising the first embed identifier and a second instruction relating to the document and comprising the second embed identifier;
• transmitting, by the device, to the first frame, the first instruction, based on the first embed identifier;
• and
• transmitting, by the device, to the second frame, the second instruction, based on the second embed identifier.

A method comprising:

• receiving a plurality of mutations, via a trusted frame, each of the plurality of mutations comprising an embed identifier;
• sorting the plurality of mutations based on embed identifiers to generate a first set of sorted plurality of mutations and a second set of sorted plurality of mutations, where the embed identifier identifies an originating frame for each of the plurality of mutations;
• applying first operational transformation rules to the first set of sorted plurality of mutations, generating a first set of instructions based on applying the first operational transformation rules;
• applying second operational transformation rules to the second set of sorted plurality of mutations, generating a second set of instructions based on applying the second operational transformation rules;
• and
• transmitting to the trusted frame the first set of instructions and the second set of instructions.
