Provide a property to add Borehole header information

[denevers]

As discussed in teleconf, we need to add header info to bhml:Borehole to hold borehole specific information (owner, drilling method, date, etc..).

we exclude metadata, because it might have a mixed semantic (such a linking to metadata about the dataset itself (who created the record, who is maintaining the dataset) as opposed to borehole header.

property should be "anyType" (at the conceptual model, modeled as "Process" class of O&M)

need to include in XSD and EAP

discussed at last telco (sept 30). Do we create a property in core for borehole details or we use "Metadata". we decided to push it to SWG

Need ‘header’ info
Need to have driller, why, how, … info
4 ways

• Metadata : … nobody wants to do it
• Add BhML:Borehole a ‘ancillaryInfo: any (0,...*)’
• Define interface to/from other standards: as in Muddi. Conceptually clear : interface in UML. Still needs tooling to implement it
• Manage it in BhML ‘Extension’: so far the Extension is EPOS Conceptual model.
