  Data science and informatics tools are developing at a blistering rate, but
their users often lack the educational background or resources to efficiently
apply the methods to their research. Training resources often deprecate because
their maintenance is not prioritized by funding, giving teams little time to
devote to such endeavors. Our group has developed Open-source Tools for
Training Resources (OTTR) to offer greater efficiency and flexibility for
creating and maintaining online course content. OTTR empowers creators to
customize their work and allows for a simple workflow to publish using multiple
platforms. OTTR allows content creators to publish material to multiple massive
online learner communities using familiar rendering mechanics. OTTR allows the
incorporation of pedagogical practices like formative and summative assessments
in the form of multiple choice questions and fill in the blank problems that
are automatically graded. No local installation of any software is required to
begin creating content with OTTR. Thus far, 15 courses have been created with
OTTR repository template. By using the OTTR system, the maintenance workload
for updating these courses across platforms has been drastically reduced.
