| "Amongst other static attributes, context elements (or rather, their observations) have various context-related attributes, i.e. attributes which are bound to a particular time and context. This generic property links this type of attributes to the elements' observations, and is not intended for direct use. Instead, specific subproperties are provided for each supported element type. In order for observations to inherit these subproperties, each needs to be typed according to the element's type (see note in dcon:Observation comment)." | 1 |
| "As context Elements can have one or more observations, this property links each of them to the respective element." | 1 |
| "At the highlest level, context information is classified under a number of context Aspects. These are provided as subclasses of this abstract class, which is not intended for direct use." | 1 |
| "Context aspects categorise elements relating to the same category of context information. Individual context elements are linked to each aspect through this generic property, which is not intended for direct use. Instead, specific subproperties for each supported element is provided." | 1 |
| "Derived from the dateTime, this property stores the exact amount of minutes elapsed since the start of the current day. Implicitly also stores the number of elapsed hours. Thus, a value of 0 means that the current day has just started whereas a value of 1439 indicates the end of a day." | 1 |
| "Derived from the dateTime, this property stores the number of days elapsed for the current month, where 1 indicates the first day of the month, up to a maximum value of 31." | 1 |
| "Derived from the dateTime, this property stores the number of days elapsed for the current week, where 1 indicates a Monday, and 7 a Sunday." | 1 |
| "Derived from the dateTime, this property stores the number of months elapsed for the current year, where 1 indicates January, and 12 December." | 1 |
| "Each context Aspect has a number of specific elements. These are linked to each aspect through the generic dcon:hasContextElement property. As this is an abstract class, it is not intended for direct use. Instead, element instances are typically inferred through the use of dcon:hasContextElement (and its subproperties) and dcon:hasObservation. Elements can have multiple observations (e.g. from a different source or device), linked through dcon:hasObservation." | 1 |
| "Each context Element can have one or more observations, e.g. from different source or device. These are linked to each element through the dcon:hasObservation property. In order to inherit the context attributes relevant for the element's type, observations need to be multi-typed. For example, each observation of a nie:InformationElement must also be defined as a nie:InformationElement instance, so that it can inherit all context attributes having the element's type in their domain specification. However, this does not mean that an observation is also an element, but merely that it must have the same type. Other defining properties of an observation are the data source (dcon:recordedBy) and the observation time (dcon:recordedAt). A validity property (dcon:validity) is also provided, and is intended to regulate the time frame during which an observation is considered valid." | 1 |
| "Links one or more active/current situations to the user. Situations are stored permanently, whether currently active or otherwise." | 1 |
| "Links the special live context representation instance to the user. Past live contexts are logged through the use of the DUHO ontology." | 1 |
| "Live context element observations have different validity periods, which mean they remain active only for a specified time interval after they have been sensed or otherwise detected. The value for this property denotes the time when the element observation's relevance expires." | 1 |
| "Records the approximate distance between a device (as a proxy for the user) and an item. Not to be confused with dcon:distanceCovered. As this context attribute can be attached to instances of ncal:Event, pimo:Location, dpo:Place and pimo:Person, the domain of this property is generalised to dcon:Observation. However, the attachment of this attribute to other instances is not considered correct application of the DCON vocabulary." | 1 |

| "This RDF Graph contains information that can be used to characterise the state of an entity, where an entity can be a user's device or the user themselves. Although this abstract class is not intended for direct use, there are two main distinguishible subclasses. dcon:LiveContext represents uninterpreted states for a user's (multiple) devices, whereas dcon:Situation represents interpreted user states. There are three levels of representation for context: Aspects at the highest level, a set of Elements for each aspect, and a number of Attributes for each element." | 1 |
| "This class represents one or more interpreted user states. A user situation refers to a generalised context graph that is derived from the merging of a number of positive and negative previous live context instances. These instances are linked though dcon:positiveInstance and dcon:negativeInstance. Unlike live context, situations are independent of time and have the possibility to recur. As opposed to live context, situations are also independent of devices and are instead user-centric." | 1 |
| "This class represents the uninterpreted state of the users as sensed through their devices. Instances of this class should be limited, since they are meant to represent realtime, 'live' raw context information as sensed through a variety of a user's devices, their applications and sensors. Although one unique instance should represent the dynamically changing live context, additional instances can be used to contain live context information for the recent past." | 1 |
| "This property assigns different weights to specific context aspects and/or elements, in order to better characterise a situation. As weights can be attached to both dcon:Element and dcon:Aspect instances, the domain of this property is generalised to dcon:Observation. However, the attachment of weights to other instances is not considered correct application of the DCON vocabulary. Expected weight values range from 0 (no impact on situation), to 1 (high impact on a situation). In addition, the dcon:isRequired property defines a necessity relationship between a context element and a situation, whereas the dcon:isExcluder property defines the inverse." | 1 |
| "This property marks those context elements which are necessary for a situation to occurr. If a required element is not active, then the correspoding situation is excluded from candidate active situations." | 1 |

| "This property ties each element's observation to the data source that recorded it, specifically data sources of type account (dao:Account subclass) or device (ddo:Device subclass)." | 1 |
