Abstract
The objective of this document is to describe the core vocabulary of the Online Laboratory Domain. It is defined as a dictionary of properties and classes that aims at providing a formal representation of the domain.
This specication was designed in order to fulfill the existing lack of a formal model to describe online laboratories and the associated resources. Classes and properties are defined using W3C's RDF technology.
This document is organized on the following way:
First a description about each class and their associated properties will be provided. Following that a description of each property including their domain and range will be presented.
Graphical Overview
On the following figure a graphical overview of the online laboratory core elements is given:

Remote Laboratory, Virtual Laboratory, Hybrid Laboratory |
The Online Laboratory Class describes an online laboratory in general. There are different types of online laboratories to which a laboratory should belong. An Online Laboratory is defined as the hardware and software platform that provides resources (experiment execution).

Experiment Class |
The class Observation Experiment is a subclass of Experiment that describes experiments where the parameters of the studied model and input are not changable.
Fixed Experiment Class

Experiment Class |
The Adaptable Experiment class is a subclass of Experiment and describes experiments where parameters as well as the structure itself might be changeable.
Lab Exercise Class
The Lab Exercise class defines an Exercise and is linked to an Experiment and a Tutorial or E-Learning Document.
Document Class
The Document class describes any media (pdf, videos, images, etc) associated to a resource.
E-Learning Material Class
This class describes all documents which can be seen as E-Learning material. It should contain theoretical background and exercises for the laboratory topic.
Tutorial Class
This class describes all documents which can be seen a laboratory Tutorial. A laboratory Tutorial can be seen as a guide through the experiment execution and different exercises.
Documentation Class
All documents which can be seen as technical documentation should belong to this class.
Scientific Field Class
The class scientific field describes the possible scientific fields covered by the online laboratories. The Scientific fields are used according to the classification in Wikipedia.
Architecture Class
The class architecture defines a fraework or structure to which a laboratory belongs (e.g. labshare, Ilabs etc.)
Client Requirements Class
The Client requirements class describes different conditions (Operating System, Browser, Run-Time engines) necessary on the machine prior to run the client application.
Subject Class
The class Subject reffers to a specific discipline that is related to a specific laboratory.
