Graph Structure
Basic Item
A basic item describes a learning content. It uses subclass of to link to a defined Cateogory, that is used to group topics. Items are linked between each other with depends on to define an item that defines some previous knowledge, or related to to link to a similar item. Additionally they link to resources with resource.
A short overview of possible links:
| Item | — subclass of → | Category |
| Item | — depends on → | Prerequisite |
| Item | — related to → | Equivalent |
| Item | — resource → | Resource |
| Item | — instanc of → | Application |
Additionally an item can be closer defined by linking an importance-item using importance. This can be done as simple link or as an added value to a property.
Resources
A Resource is an item that is defined by the Properties url to link to an external site and instance of a structure-item, as seen below.
A short overview:
| Resource | — url → | URL |
| Resource | — instance of → | Structure-Item |
See: Item:Q280 as an example and Resource to reference a dummy element
Category
A general category, such as "Mathematical Foundations"; used to group topics.
A short overview:
| Category-Item | — instance of → | Category |
A Course can include
Course
A course encompasses a collection of learning contents. To declare an item as a Course use instance of.
A short overview:
| Course-Item | — instance of → | Course |
| Course-Item | — taught by → | Educator |
| Course-Item | — includes → | Session |
See: Item:Q170 as an example. A course can include a Session, as seen below:
Session
A Session acts as a possibility to group several items that will be discussed during an actual course session.
See: Item:Q248 as an example.A short overview:
| Session-Item | — instance of → | Session |
| Session-Item | — includes → | Item |
| Course-Item | — on date → | Date |
People
Student
The role of a student is declared by linking from an item to Student using instance of. The student then can link their item to others using interested in and has completed to organize their interests and progress.
A short overview:
| Student-Item | — instance of → | Student |
| Student-Item | — interested in → | Item |
| Student-Item | — has completed → | Item |
See: Item:Q315 as an example.
NOTE: Query currently only shows one property label, the other would be "has completed".Educator
