Got it. sorry I copied from the email.
Quick follow up - I altered the tags like this -
(class +Item +Entity)
(rel ttl (+IdxFold +String))
(rel tgs (+List +Joint) itm (+Tag))
(rel sts (+IdxFold +String))
(class +Tag +Entity)
(rel itm (+Joint) tgs (+Item))
(rel v (+Ref +Link) NIL +TagVal)

Well, yes, but this is the previous version which I wrote in a
wrong way.
To get all blue ones: (collect 'n
Thanks Alex/Beneroth,
Okay ... just to clarify. (collect 'nm '+Tag "BLUE" NIL T 'itm) is the
recommended way to get to all items for a given Tag.
I should perhaps use an indirection to +Tag class so that I do not repeat
it every time.
After some thinking it seems that perhaps I could just go with

Correct, makes sense only for strings, as it indexes substrings.

Hi Kashyap
Try: (rel tgs (+List +Ref +Joint) NIL itm (+Tag))
+Idx is for +String, actually a special variant of the general
non-unique index +Ref.
Be aware that the relation classes may have parameters - in same order
as the prefix classes:
(rel ( ... )
...
)
Now I'm currently unsure if +Ref

No, it makes no sense to add an index to a +Joint. Because the object *is*
already reachable via the joint's back link.
What *does* make sense is (+Ref +Link), which is equival
Thanks Alex,
How can I add +Idx to tgs? That should be possible right?
When I add +Idx to tgs, I get "tgs -- No Link" error.

No problem Alex,

returns NIL. For that matter, even (collect 'tgs '+Item) returns NIL. I

Hi Kashyap,
sorry, I was busy! I did not find the time to install and deeply check all your

Okay - I've got the answer to the second question as well. I am not sure of
the efficiency though - I essentially collect all items that have the tag
RED and then collect all the items that have the BLUE and then do "sect" on
the output lists. Is this reasonable?

Hi Alex,
I think I have a workaround for my question 1 :) - if I use the status as
an inline relation instead of a link that is. I can use use "filter" in the
select to get only items of a given state. I was wondering if there is a
way to filter based on a Link relation though. My question 2 is sti
Hi Alex,
I have a couple of follow up Pilog questions.I've been doing some trial and
error and I don't see it converging :)
I have written a statndalone script for this so that you can easily tell me
how to do it in it. In the script below, the entity relation defines three
types - Item, Status an

The concatenation of multiple collects is just what I need :)

Hi,
My ER model looks like this -

(rel dt (+Need +Ref +Date))
