A Core Building Block
Domain is an xAPI vocabulary extensions type in the GBLxAPI profile used to represent terms and specific URIs at a high level of an educational category. In educational standards, they are often referred to as domains or a discipline.
xAPI Extension - Topic
The "Topic" xAPI context extension includes over 110 gblxapi URIs that support common contextual references for topics and diciplines for english language arts, math, science, and social studies. The URIs are part of the GBLxAPI vocabulary catalog to improve data normalization and interoperability across k-12 educational applications. The URIs were developed during the research phase of this community project.

GBLxAPI provides permanent URIs that can be used as ids related to the topic extension. These are context related to the learning experience. An example for math topic would be Expressions. The URI id used in the array would be:
