Alexander Klimetschek commented on SLING-2477:
----------------------------------------------
I suggested the service.ranking{int} syntax mostly because it's more visible
and intuitive.
It would also use the "closest" JCR property type instead of always a string
(what the I"1000" notation implies):
- byte => LONG
- short => LONG
- int => LONG
- float => DOUBLE
- char => STRING
If values exceed their interval, we can either take a best effort (first char
of a string or maximum byte/short/int/float value), ignore them or throw an
error. Don't know what's best.
For completeness, the ones hat map 1:1:
- string => STRING
- long => LONG
- double => DOUBLE
- bool => BOOLEAN
The types that are in JCR, but not in OSGi config admin, can be ignored. Maybe
the implementation uses the JCR property toString() mapping and sees them as
string properties (if that already happens in the current version).

> URL: https://issues.apache.org/jira/browse/SLING-2477
> Project: Sling
> Issue Type: Bug
> Components: Installer
> 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}".
