Open Geometry Textbook

The Open Geometry Textbook project attempts to design and implement a web-based platform for acquiring geometric knowledge to form textbooks via the collective intelligence of a massive number of web users (or netizens including geometry experts, teachers, learners, and amateurs). An open textbook is a running software system that appears as an electronic, dynamic textbook and is freely accessible. Netizens are allowed to revise the contents of the textbook and can review the latest revisions and assess them using implemented mechanisms. When the assessments of revisions are justified, the textbook is updated automatically in real time and its new version is then published online. Compared with collaborative platforms like Wikipedia and Connexions, domain knowledge collected in the open textbook will be formalized, more focused, and better structured, so software tools can be developed or integrated to automate the process of theorem proving, diagram generation, consistency and soundness checking, textbook version maintenance, etc. and thus assist to validate contributions.
