## 6.5 PS3.5: Data Structure and Semantics

PS3.5 of the DICOM Standard specifies how DICOM applications construct and encode the Data Set information resulting from the use of the Information Objects and Services Classes defined in PS3.3 and PS3.4 of the DICOM Standard. The support of a number of standard image compression techniques (e.g., JPEG lossless and lossy) is specified.

PS3.5 addresses the encoding rules necessary to construct a Data Stream to be conveyed in a Message as specified in PS3.7 of the DICOM Standard. This Data Stream is produced from the collection of Data Elements making up the Data Set.

PS3.5 also defines the semantics of a number of generic functions that are common to many Information Objects. PS3.5 defines the encoding rules for international character sets used within DICOM.
