  1. Technical DataProposal 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 datatables

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

  4. use cases (2) Publishing • Filtering or transformation, targeting different unit systems • 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))> <!ELEMENT datatype (#PCdata | .... )*> <!-- mixed content for the defintition of datatypes --> <!ELEMENT si-value (number, unit)> <!ELEMENT us-value (number, unit)> <!ENTITY % value "si-value?, us-value?"> <!ENTITY % value „((si-value, us-value?)| (si-value?,us-value ))">alternatively <!ENTITY % numberunit "(#PCdata | ....)*"> <!--mixed content for the defintition of units--> <!ELEMENT number (#PCdata | .... )*> <!– only numbers /floating point ? --> <!ELEMENT unit %numberunit;> <!ELEMENT upper-value (%value;)*> <!ELEMENT lower-value (%value;)*> <!ELEMENT tolerance-asymmetric-value ((tolerance-high-value, tolerance-low-value?) |tolerance-low-value)> <!ELEMENT tolerance-high-value (%value;)> <!ELEMENT tolerance-low-value (%value;)> <!ELEMENT tolerance-symmetric-value (%value;)> <!ELEMENT textdata (#PCdata | .... )*>

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

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

  9. examples (2) <techdata > <datatype >Operating weight </datatype> <si-value><number>481 </number><unit>kg </unit></si-value> <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)

  10. examples (3) Tables of techdata-elements <techtable> <techdata>…</techdata><techdata>…</techdata><techdata>…</techdata> <techtable> language dependent (automatically published)table headers tolerance-symmetric-value lower-value, upper-value

  11. examples (4) techdata elements within CALS tables Prospect/Dev: <techdata source=“sql:‘select $value from …where…‘ “ > <techdata source=“ws:$value,$ype,…“ >
