[tomas-knap]

1. Export any/all dpu templates under t-sparql dpu template, e.g., [CSSZ] Dim Duchody 2 (cuni-test1).
2. Try to import it to cuni-test2.

So probably it was not tested to import DPU template which is derived from another DPU template (3rd level DPU templates in the tree)

As a consequence, we are not able to export/import sk datasets pipelines, because they use dpu templates based on t-sparql! So if we go for new release these days, this must be fixed there

one can always create same templates manually

Well, if you have hundreds of SPARQL queries, it is not that useful. For sure, there are hundreds of queries within t-sparql template at cuni-test1 - that means at least one or two hours of work for import to one instance!

I guess that what is needed is to add the following logic:

• when importing DPU templates, first import those which are 2nd level DPU templates (the JAR files).
• then, import the rest of the DPU templates. When importing 3rd level DPU template which is based on an existing DPU template (t-sparql, 2nd level in the DPU tree), then, when importing such dpu template, if there is no JAR file for the imported 3rd level DPU, report error (that is simple and enough in the first round). If there is already such JAR file with the same version (could be realized by checking the artifact ID + version in the JAR file name, so basically comparing the refereed JAR file name), continue and create DPU template under this DPU template.

So it is about one boolean in the export to know which templates are second level templates (t-sparql) and which are third level (particular t-sparql with the particular configuration)

How differs template in 2nd level from 3rd level template?
How differs template in 2nd level from 1st level template

[tomas-knap]

1st level in the DPU tree - type of DPU template - 3 types - extractors, transformers, loaders
2nd level DPU template = root DPU template, i.e., the template which defines new JAR file and default configuration (e.g. t-sparql)
3rd level DPu template = DPU template which uses the same JAR file as the parent root template, but overrides the default configuration of root template to a new default configuration (e.g. t-sparql with a set of three particular SPARQL update queries)

Let's talk further about root DPU templates (2nd level) and dependant DPU templates (3rd level), which uses JAR file of its parent root template and overrides its configuration.
