How very rdf:Statement of you!

Since attribute is just another datom in Datomic you can do:

[?p ?a ?p2]
[?a :db/ident :friend]

[?p ?e ?p2]
[?e :attr/ident :friend]
[?e :date ?date]

[?p ?e ?p2]
[?e :attr/ident :friend]
[?e :priority ?p]
[(> ?p 10)]  ;; and maybe in find we want to (count ?e)

Since this is the Asami channel, I can say that this is already quite possible. In fact, we’re using it this way at Cisco.

While it has bizarre semantic implications (that I really don’t want to think about! :rolling_on_the_floor_laughing:) Asami has been liberating after years of RDF where the datatypes of Subject/Predicate/Object were so strictly defined

So Asami really just doesn’t care if your attribute is an internal node that is unique to that connection and has its own attributes

Asami also doesn’t care if your attribute is a string… which has its own attributes.

(Note: please don’t do this! It works fine, but I’m sure that one day it will cause significant confusion for someone)

I like the idea that I can say:

["football"  :matches  #a/n 1]
[#a/n "1"    :type     :regex]
[#a/n "1"    :value    "^foo.*"]

Asami 2.0.2 is out. This has 2 changes: • A bugfix in grouping for some aggregate queries • Filenames have been corrected. If you have a database from 2.0.1 or earlier, then you can rename the files with a script called update.sh on github

The filename change was annoying and trivial, so I didn’t figure that it warranted a minor version update, but it’s a bigger change than I like.

I figured I needed to get it out asap before too many databases had been created with the wrong filenames 🙂
