CSC/ECE 517 Fall 2017/Semester Project - Implement the Microdata API
Background
This project is the second phase of the OSS project - M1752 Implement the Microdata API. Please refer to the phase 1 documentation on the Wiki prior to going through this document to gain familiarity with the components involved and build instructions
Introduction
Servoshell
Servoshell is a work-in-progress front-end for the servo browser engine.
Scope
The scope of this project is to implement algorithms to interpret JSON and vCard data present in the form of microdata, in a webpage and to notify the embedder, in this case servoshell. This would allow the embedder to display this data as required.
The following steps are to be performed -
1) Implement and test the algorithm to extract JSON from microdata. Specification Details
2) Implement and test the algorithm to extract a vCard from microdata. Specification Details
3) Use these algorithms to extract metadata from each page after it finishes loading and send it to the compositor
4) Notify any embedding code of the newly-extracted metadata
5) Modify the servoshell embedding to use the new notification and create a vCard file if available
Design
The below diagram provides details on the components involved in the process flow for the changes in scope
The diagram below outlines the sequence of operations that take place in order for servoshell to interpret the microdata.
