ANSWER
Answered 2021-Jun-08 at 12:56With a touch of caution, it might be worth trying to parallelise these to reduce the overall time. But you might hit some other bottleneck.
This is not tested, but hopefully might be enough to help you to give it a go:

To make it work, You need to define some meaning to your properties ex:isPartOf
and ex:livesIn
.
Suggest to make ex:isPartOf
transitive and then to define ex:livesIn
as a property chain over ex:isPartOf
, e.g.:

I want to get xml input file via the MarkLogic CoRB Tool to proceed further, but not able to get this file via CoRB tool:
ML config Properties file:
...ANSWER
Answered 2021-Jun-07 at 21:24The CoRB StreamingXPath is not currently able to register and leverage namespaces and namespace-prefixes, so the XPath targeting namespace-qualified elements can't leverage namespace-prefixes.
A more generic match on the document element with a predicate filtering by local-name()
will work though. It's a little ugly and a lot more typing, but works:
QUESTION
I don't even know what title this question should have.
So, I am working on a library to make Google-Billing
as easy as possible to integrate.
Everything started after I've upgraded the library to Google's Billing v4
which replaces Purchase#getSku
with Purchase#getSkus()
.
This is the before and after migration to billing v4
:
Before (v3 library):
...ANSWER
Answered 2021-Jun-07 at 10:27In V4.0 BillingClient method callbacks call in background thread, not in Main thread.
Workaround is to change thread to Main in BillingClient callbacks.
Call you method processPurchases() with Toast in UI thread.
QUESTION
I would like to convert NCBI's Biosample Metadata XML file to CSV, or RDF/XML as a second choice. To do that, I believe I have to learn more about the structure of this file. I can run basic XQueries in BaseX*, like just listing all values, but then I've been using shell tools like
sort|uniq -c
to count them. I have heard about XSLT
transformations and GRDDL
in passing, but I don't think a style sheet is provided for this XML document, and I don't know how to create or discover one.
For example, can I get a count of the number of s for each ? Are there any
with more than one primary
? What are the most common db attributes of the primary Ids?
Here's a query that shows my maximum level of XQuery sophistication at this point:

QUESTION
I have the following json merged with context below,
Currently I am facing 2 problems
1 the duplicate keys or properties that are present in the JSON at different levels how to deal with those so I can have the correct triples connected to each other?
2 @vocab is ignored where I have use @id like on rowid and it adds a default prefix in json-ld playground
...ANSWER
Answered 2021-Jun-02 at 17:39By "duplicate keys", I presume you mean the same term used as a property key at different levels of the JSON document. For this, JSON-LD has the notion of a Scoped Context, whereby you can have a context come into play inside of the value of some property, or where a type is in effect. In this way, for example, you could define "value" to map to one IRI at the top level, and within the term definition of "value" (or some other intervening property), define a new context which redefines the mapping for "value"
Regarding @vocab
and @id
, @id
is considered a document-relative term, and string values are expanded from the document base, or @base
, if defined in the active context (see section 4.1.3 Base IRI). @vocab
is used for expanding vocabulary-relative term such as @type
and object property keys, which aren't otherwise defined as terms (see section 4.1.2 Default Vocabulary.
QUESTION
Could you please tell me, is it possible to implement such case by just OWL ontology definitions? Or I need to create custom rules for it?

QUESTION
I am struggling to write a SPARQL query to fetch a list of products by the owner along with a count of other owners.
following is the query i expect to get the result
...ANSWER
Answered 2021-Jun-01 at 17:10SPARQL Query semantics specify how portions of the query are joined together. Your sub-query does not project any common variables that are shared with the outer query. It only SELECT
s the ?allOwners
variable which does not appear in the rest of the query.
This means that you get a cross product of all the counts and all your other results; this is why you get duplicate rows and no correlations between the counts and rows.
This kind of query can be achieved if you structure it correctly. Since you haven't provided example results you desire, I'm having to make a best guess of what you want. Something like the following may have the desired results:

function.
QUESTION
Apache Jena is not able to query RDF Star Triples that have a double data type in them. Here is the code for reproduction of the issue with Jena 3.17 (it can be reproduced on other versions too).
...ANSWER
Answered 2021-May-30 at 17:14It works in Jena 4.0.0.
In 3.17.0 - SPARQL was more like the original RDF* in its use of indexing.
As a consequence, the non-canonical term map cause a problem.
Try a lexical form of "1.0e0"^^xsd:double
or v 4.x.x.

Install rdf
Copy all the module files into a subdirectory called sites/all/modules/rdf/ under your Drupal installation directory.
Install the ARC2 library following one of these 2 options: run "drush rdfx-arc2" (recommended, it will download the right package and extract it at the right place for you.) manual install: download the library from http://arc.semsol.org/download and extract it in the rdf module directory such that you end up with the following file structure: sites/all/modules/rdf/vendor/arc/ARC2.php
Go to Administer >> Site building >> Modules and enable the RDFx module and any other module you like. You will find them in the "RDF" section.
