Hello everybody,
Since I am working on the conversion from the dump files to the wdtk
data model, I will have to take apart the "refs" section of the JSON
representing the stored items.
Now a "refs"-section most likely looks like this:
(Tried to format it for readability)
"refs":
[
[
[
"value",248,
"wikibase-entityid",{"entity-type":"item","numeric-id":15241312}
],
[
"value",577,
"time",{"time":"+00000002013-10-28T00:00:00Z","timezone":0,"before":0,"after":0,"precision":11,"calendarmodel":"http:\/\/www.wikidata.org\/entity\/Q1985727"}
]
]
]
So I figured out the following: The outer array groups all references.
The second level array groups information about one reference (so if we
had multiple references, we would also have multiple second-level
arrays) and the inner arrays each group one specific information about
one specific reference (as determined by the second level array they are
nested in).
Am I correct so far?
The integer following the "value"-string denotes what the following
information is about. So if I read that the value is 577, I know that
there must be a specification of time, don't I?
Is there any specific reason, why this is done in array form and not in
a JSON object? (Since the "value"-key is always there one could know
from its value, what other keys must be available.)
If yes, why mention the type of information (e.g. "time") again?
Am I overlooking something?
Thanks so far,
-- Fredo Erxleben
