I few things that are not falling out from documentation that i wonder
whether they make sense to try or to ignore:
CDE - is this still a thing?
What does CDE stand for?
SpinMap - doesnt seem to be supported in other technology layers (how
to access it via SPARQLMotion and/or SWP ?)
SPINMap should work fine - it is just a collection of SPIN templates
with a visual notation. The SPIN templates can be executed as rules
using the normal SPIN infrastructure including sml:ApplyTopSPIN (which
also happens to be accessible using SWP). SPINMap is for example used
under the hood of the EDG spreadsheet importers.
Import using XSD - this only seems to be supported using a manual
import wizard - SM or SWP support to make it reusable?
It's a TBC only feature right now. The multitude of configuration
options would make it bulky to expose through other means.
In XML import, where a XML attribute is an object id and objects
reference each other, XML import treats these as DatatypeProperty
(literals) and loses all the interesting object relationships - is
there a way of handling this elegantly?
In many use cases, the XML importer is just used for the raw data
lifting, and then SPIN or SHACL rules are used to copy thing into
"proper" RDF triples.
Another option is to do XML processing as a preprocessing step, e.g. XSL
(for which there is also SPARQLMotion support).
XML import in general - does importing with an XSD produce something
substantially different from SPARQLMotion XML->RDF module? What is the
recommended way of doing an XML import and conversion in a SWP
environment?
The recommended way is to produce a stable Semantic XML ontology that
has sxml: annotations at classes and properties. These ontologies can be
either created by hand, generalized from example instance files, or
through the XSD importer. Then use sml:ConvertXMLToRDF to convert XML
instance documents.
