Carsten Ziegeler commented on SLING-2477:
-----------------------------------------
I still think this is something that has to be fixed in the JCR spec, although
the name is "Java" content repository it does not support the basic
types....but well, definitely not something we can fix here.
I think, Ian's first approach to use the " like I"100" seems to cause the least
problems. Having a separate property for each property with the type is too
confusing.
Now, in addition we only need the type information if the type is not supported
by JCR, so no extra information required for strings, longs or booleans - we
need it for float, int, byte, char, and short.
So we either store these as string properties in the format
[TYPE_INFO]"[value]" - or the other solution I see is we store a single
additional property containing the type information. Like a string array with
values in the format [name]:[type]. The value itself is then stored as a string.
However, having a single property is easier to handle and maintain.
Once we have this, I agree we should create a new issue to improve SLING-1971
and support write back of both, config nodes and config files - depending on
their previous format.

> Affects Versions: JCR Installer 3.1.2
> Reporter: Alexander Klimetschek
> Assignee: Ian Boston
>
> Most notably, the common "service.ranking" needs to be an Integer, while the
> jcr property mapping only allows for "Long" types at the moment. The problem
> is that JCR has a smaller set of property types than the OSGi config admin
> (JCR: String, Boolean, Long, Double, Decimal; OSGi: String, Boolean, Long,
> Integer, Float, Double, and probably more differences...).
> Similarly to properties files (which do it in the value like
> 'service.ranking=I"-10000"' with I=Integer), there must be a way to
> explicitly specify the type regardless of the JCR type. For example, encoding
> it in the property name like "service.ranking{int}".
