¶ Introduction
A new DCC schema version 3.4.0-rc.2 has been published for the DCC schema. The schema is for temporary purposes only, it is due to changes.
The release candidate is intended for interested testers only and is solely for testing purposes. Content may change during development.
¶ Changes:
¶ Measurands
¶ New Types:
- measurandListType
- measurandType (see picture above)
- informationSourceListType
- informationSourceType
- measurandSpecificationListType
- measurandSpecificationType
- noWhitespaceStringType: new type to define lists of strings more clearly, lists of strings without space characters separated by space e.g., "aa bb cc"
¶ Modifications
- dcc:measurands in dcc:measurementResults
- dcc:measurands in dcc:measurementResult
- dcc:measurands in dcc:list
- dcc:measurands in dcc:quantity
- charsXMLListType: base type is now dcc:noWhitespaceStringType instead of xs:string in order to enforce by schema that charsXMLListType is a list of strings without space characters separated by space.
- refTypesType: base type is now dcc:noWhitespaceStringType instead of xs:string in order to enforce by schema that charsXMLListType is a list of strings without space characters separated by space.
- stringWithLangType: base type is now dcc:notEmptyStringType instead of xs:string
- conditionType: added states - beforeCleaning, afterCleaning, noAdjustment, noCleaning,noRepair
- primitiveQuantityType: added metaData to primitiveQuantities
To process tables correctly, specify the number of independent quantities in dcc:list using the dimension attribute, and index each quantity in dcc:quantity with the index attribute.
- New attribute tableDimension in listType
- New attribute index in quantityType
- New attribute index in primitiveQuantityType
¶ XML Example for measurands
This is just an example and not from a production release DCC.

¶ How can the release candidate schema be used in DCC XMLs?
Only two changes are necessary in the current DCC to use the release candidate.
