Technical Data Proposal MI 10 W. Ziegler University of Applied Sciences, Karlsruhe (19-02-2008)
2
goal Semantic data model for technical data Automatic 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 „data“ within mixed content) b.Editing logical tables of technical data (element „techdata“ within topic structure)
4
use cases (2) Publishing a.Filtering or transformation, targeting different unit systems b.Publishing tables of technical data (logical/“techdata“ 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 data (datatype?, ((si-value?, us-value?, (tolerance-asymmetric-value | tolerance-symmetric-value)?) | (lower-value, upper-value) | textdata))>
7
basic semantic model (3) Logical tables of technical data During publishing, columns are set by the datatype, unit/number-combinations or textdata.

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

examples (2) Operating weight Operating weight 481 kg 481 kg <us-value><number>1060.4</number><unit>lbs</unit></us-value></data> 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)
