How to correctly create and use open educational resources, which focuses on wikisystems.

Many problems arise in regard to ensuring OER WMS quality. The primary problem is ensuring the long-term sustainability of the resource, primarily from a personnel perspective, i.e. via properly functioning communities. To do so, it is necessary to compensate for the departure of some staff members by accepting new ones. Factors that can discourage newly arriving members include any type of closed resource (i.e. no opportunity to contribute to it) and being forced to take part in its creation (e.g. in the form of school responsibilities); it is shown that communities of these resources function better on voluntary cooperation and possibilities of broad, open collaboration so that interested external parties can also become engaged in them.
