1. Technical Data Proposal MI 10 W. Ziegler University of Applied Sciences, Karlsruhe (15-04-2008)

2. goal Semantic data model for technical data Automatically transformation and processing of metric, none-metric technical data and corresponding tolerance values Publishing of technical data tables

3. use cases (1) Editing process a.Including technical data at text level (element „techdata“ within mixed content) b.Editing logical tables of technical data (element „techtable“ within topic structure)

4. use cases (2) Publishing a.Filtering or transformation, targeting different unit systems b.Publishing tables of technical data (logical/“techtable“ or generic/CALS)

5. basic semantic model (1) Includes metric („SI“) and non-metric („US“) unit systems Includes semantics of tolerance data

6. basic semantic model (2) <!ELEMENT techdata (datatype?, ((%value; (tolerance-asymmetric-value | tolerance-symmetric-value)?) | (lower-value, upper-value) | textdata))> alternatively alternatively

7. basic semantic model (3) Logical tables of technical data During publishing, columns are set by the datatype, unit/number-combinations or textdata.

8. examples (1) <techdata> Operating weight Operating weight 481 kg 481 kg </techdata> Rated speed Rated speed 2500 min -1 2500 min -1 </techdata><techdata> Engine manufacturer Engine manufacturer <textdata>MC</textdata></techdata> Operating pressure Operating pressure <!– published e.g. as 210 (+5/-10) bar  210 210<tolerance-asymmetric-value> 5 bar 5 bar 10 bar 10 bar </tolerance-asymmetric-value></number><unit>bar</unit></si-value></techdata>

9. examples (2) Operating weight Operating weight 481 kg 481 kg <us-value><number>1060.4</number><unit>lbs</unit></us-value></techdata> Allows output filtering, if both units are included by the author Allows automatically localization/transformation, if only one unit system is included (unit system must be apparent at topic level/metadata) Filtering and transformation is triggered by output specification (map attributes)
