Getting All Properties Std. and Custom
Dear all,
In Slide there are some standard properties like dispalayname,
contentlenght... etc. A user also can make some custom properties. I user
make custom properties in DAV: namespace then my question is:-
Is there is any way to get all DAV: properties including Standard as well as
userdefined properties in the slide.
I ONLY WANT UNIQUE PROPERTIES. means First get STD. properties i.e. 12-15
and user defined properties , no duplicate. IN ALL THE RESOURCES.
My motto is , i want to make a combo box to show user all the properties
avalilbale to him.
Thanks in Advance

Hello Aslam,
If you're asking about the last remark, it's just a simple workaround for a
property list management. As an example, you could use this solution: create
a DB table with a OID and string called PROPERTY_NAME. Then use your
favourite O/RM tool to access the database table and allow you to read and
write into it. When you need to find all defined custom properties, just
list the contents of that table.
Another way to do this, witch I called creepy (you have to figure out how
the persistence model works) in the last mail, was to access slide database
tables, and query them for distinct property names.
Hope this helps,
Miguel Figueiredo

Hi Miguel,
Yes you got my point, what i need. You have given me suggestion. Can you
little more explain on your idea , how to do that.

Hello Marco, Aslam,
Don't know how I missed Julian's remark on availability of this kind of
query, so cut out the first part of my previous message, leaving only second
part, witch would still work although it kind of creepy (accessing Slide's
meta information DB directly).
Anyway, concerning Marco question transcribed below. From what I
understood, Aslam wants to know, with one request, every custom property
defined in the repository. He would next populate a list with it, so users
could use the same property instead of creating new similar ones. Means that
the request should be done globally in the repository, and that's thousands
of documents. Because the query must be done globally, I would not advise to
make a query for every resource in the repository and then filter down on
client side (even client side): just imagine matching 100 000 documents,
building a DASL result of it (xml), and then parse it.
Aslam, you could do it easily if you managed the possible property list
outside Slide (keeping a property name list in a configuration file or DB,
and then retrieve that information instead of querying Slide).
Hope this helps,

Hi Aslam ,
as Julian already told you, it is not possible to create a query that
filters
by namespace. What you have to do is filter your data "manually" after the
DASL query's been performed.
Actually, apart from the possibility to create a query that filters your
data
server side ( and which we discovered not being possible) , I don't see ( =
understand ) why you need to know the number of custom properties for each
resource BEFORE parsing the result of the DASL query.
ciao

Ok ,
First of all it is not possible in my program. Because in my program a user can make a property in only one custom namespace which is defined by my program and hide from user. So now there are only two namespace DAV: and my custom namespace. So, Now i can get standard DAV: properties of a resource which are not more than 15-16. But what about custom namespace properties because i don't know on which resource and by what name and how many properties a user has given. Help Plz.

Hi Aslam,
let me see if I get your question :
you have a property named displayname in a namespace that's not the
default, let's say FOO. Then, in you r application, you have a listbox
that lists all the properties without showing the namespace, hence
displayname would be duplicated. What you need is that your
application shows only one displayname, the one that refers to FOO.
If I get your point :
you need to filter the properties after the DASL query ( I don't rekon
it is possible to creeate a query that filters on namespaces but I may
be wrong here ) .
Question : what should happen if there are three or more instances of
displayname and different namespaces ?

Hello Aslam,
I believe it's possible, but not sure, that DASL supports your query
(Julian is the expert there). And it doesn't need to be very performance
expensive if you activate slide's integrated indexing. You can find some
instructions for that in here:
http://wiki.apache.org/jakarta-slide/DaslConfiguration
The link also suggests another option, witch would be accessing the
metainformation database directly, and perform your 'DISTINCT' sql query.
Hope this helps,
Miguel Figueiredo

You can select properties by property names, but that doesn't allow
wildcards (such as all properties in a certain namespace). See

Hi Julian, Thanks for reply.
I am making cusotm properteis using DAVExplore and now i am making the
properties in "CUSTOM:" namespace. Now the questions are:-
1.) I am giveing propfind method with <allprop/> , it is giving me all the
properteis of all the resources. The properties names like displayname,
creationdate .. repeated for every resource. But i want only to get unique
names of properties. If i am giving this request, then it is performance
issue and very havy. Is not there is a way to get all unique properties
names.
2.) How to search or get allprop in my Custom namespace.
