The DSNotify eventset vocabulary can be used to describe timely-ordered sets of events that modify resources in linked data sources. Eventsets are associated with two void:Datasets: a source and a target dataset. A complete eventset contains all events that -- when executed in the proper order -- change the source datasets into the target dataset.
NOTE: this is a re-publication of the original DSNotify eventset vocabulary that was available at http://dsnotify.org/vocab/eventset/0.1/

The namespace of this document is

The suggested namespace prefix is evset.

Term	Type	Definition
UnknownEvent	class	An event class describing that a not further specified event occurred to a resource in a dataset.
UpdateEvent	class	An event class describing that a particular resource was 'updated' in a dataset. This means that some triples having the associated resource as subject or object were modified/created/removed in the corresponding RDF model.
RemoveEvent	class	An event class describing that a particular resource was 'removed' from a dataset. This means that all triples having the associated resource as subject or object were removed from the corresponding RDF model.
Eventset	class	An eventset is a container of events that occur in a dataset.
void:Dataset	class
ResourceChangeEvent	class	An event that changes the representations of a resource in an RDF dataset. ResourceChangeEvents are lode:Events and the lode:atTime or the lode:circa properties should be used to describe the time when the event took place.
scv:Dimension	class
lode:Event	class
MoveEvent	class	An event class describing that a particular resource was 'moved' in a dataset or between datasets. This means that all triples having the associated older resource as subject/object were replaced by triples having the target resource as subject/object in the corresponding RDF models.
CreateEvent	class	An event class describing that a particular resource was 'created' in a dataset. This means that one or more triples having the associated resource as subject or object were created in the corresponding RDF model.
hasReason	property	A link to a resource that further specifies the reason for the respective ResourceChangeEvent. For example one could attach a textual description or link to another event here. This property is under-specified in this version on purpose.
hasAffectedTriples	property	A link to a resource that further specifies the actual triples that were added/removed in consequence of the respective ResourceChangeEvent. For example one could attach a Talis changeset here. This property is under-specified in this version on purpose.
targetDataset	property	A void:Dataset that is considered as 'target' dataset of the associated eventset. When the eventset is 'complete' and all events are applied in their timely order to the corresponding source dataset(s), this dataset (and all other target datasets) should be the result. Example: a static snapshot of a dataset at time t0+delta, e.g., the DBpedia snapshot 3.3
sourceDataset	property	A void:Dataset that is considered as 'source' dataset of the associated eventset. When the eventset is 'complete' and all events in this eventset are applied in their timely order to this and all other source datasets, it will become equal to the corresponding target dataset(s). Example: a static snapshot of a dataset at time t0, e.g., the DBpedia snapshot 3.2
hasEvent	property	An event that is part of an eventset.
hasConfidence	property	Optional property for capturing the confidence (a float value between 0 and 1) the event detecting actor has that the corresponding event really took place. If omited, applications should assume a confidence of 1.0.
targetResource	property	The identifier (URI) of a resource that was affected by the corresponding event.
sourceResource	property	The identifier (URI) of a resource that was published under a new URI (i.e., when a MoveEvent occurred).

The DSNotify eventset vocabulary was originally developed for the evaluation of DSNotify. It was used to describe events that change a particular source dataset (e.g., DBpedia 3.2) until it is equal to a corresponding target dataset (e.g., DBpedia 3.3). The overall evaluation strategy of DSNotify is depicted in the figure below: An eventset and two associated datasets are fed into a simulator that applies the events in the eventset in their timely order to the source dataset using a compressed timeline (i.e., one can configure how long the simulation runs). This continuously updated dataset is monitored (observed) by DSNotify that reports detected events back to the simulator. Finally, the detected events are compared to the eventset events and an evaluation result is calculated.

The DSNotify eventset vocabulary was used for the description of eventsets changing DBpedia snapshot 3.2 into DBpedia snapshot 3.3 and for describing changes between corresponding models in the ISLab Instance Matching Benchmark.
