byteSize

The overall size of the data object in bytes. That means the space taken by the DataObject in its container, and not the size of the content that is of interest to the user. For cases where the content size is different (e.g. in compressed files the content is larger, in messages the content excludes headings and is smaller) use more specific properties, not necessarily subproperties of this one.

characterSet

Characterset in which the content of the InformationElement was created. Example: ISO-8859-1, UTF-8. One of the registered character sets at http://www.iana.org/assignments/character-sets. This characterSet is used to interpret any textual parts of the content. If more than one characterSet is used within one data object, use more specific properties.

The size of the content. This property can be used whenever the size of the content of an InformationElement differs from the size of the DataObject. (e.g. because of compression, encoding, encryption or any other representation issues). The contentSize in expressed in bytes.

Data Source Graph

Represents the sum of all information that has been obtained from a data source. Each data source has its own personal information graph. When a data source is deleted, the graph becomes redundant and should also be deleted. If two or more items in two or more data source graphs are determined to be equivalent, they are integrated at the PIMO level, and the integrated representation plus the links to the original items are stored in the pimo:PersonalInformationModel graph.

DataObject

A unit of data that is created, annotated and processed on the user desktop. It represents a native structure the user works with. The usage of the term 'native' is important. It means that a DataObject can be directly mapped to a data structure maintained by a native application. This may be a file, a set of files or a part of a file. The granularity depends on the user. This class is not intended to be instantiated by itself. Use more specific subclasses.

DataSource

A superclass for all entities from which DataObjects can be extracted. Each entity represents a native application or some other system that manages information that may be of interest to the user of the Semantic Desktop. Subclasses may include FileSystems, Mailboxes, Calendars, websites etc. The exact choice of subclasses and their properties is considered application-specific. Each data extraction application is supposed to provide it's own DataSource ontology. Such an ontology should contain supported data source types coupled with properties necessary for the application to gain access to the data sources. (paths, urls, passwords etc...)
