Here's another strawman, based on Carsten's example, of a = potential design with array of sdfObjects:
https://github.com/one-data-model/exploratory/blob/master/sdfTh= ing/fridgemultifreezer.sdf.json

It uses = new "minItems" and "maxItems" qualities (similar to JSO min/maxItems for = array type) to define how many freezer Objects can there be in the = Thing.

This seems like a reasonable design, = but there are still open questions like how to address those objects. = One option is to use JSON pointer array syntax, e.g., a pointer to the = 7th freezer object could look like:
#/sdfThing/FridgeMulti-freezer/sdfObject/freezer/6

However, given the definition is not an actual = array (it's JSON object with two new qualities), something like = additional processing steps on the model would need to be applied before = the JSON pointers can be used as such.

Another question is whether we should have minItems quality = or should we use only sdfRequired also here. Unless we want to invent = new wildcard syntax for sdfRequired, seems that sdfRequired would need = to have separate pointer for each required instance. That could result = in excessively large sdfRequired blocks so minItems seems like a = reasonable shorthand for that.

We have: * title (just some human-readable text) * version * copyright (legal) * license (legal) Today in the OneDM playground, the version quality simply contains a = date string (ISO 3339 style, "2021-04-19=E2=80=9D). Beyond the date information, we now seem to discuss pressing a lot of = other information into the version quality: =E2=80=94 semver (1.2.3, major/minor/patch),=20 =E2=80=94 token holder (who is expected to be evolving that spec) =E2=80=94 date (what exactly is the date this is about?) =E2=80=94 feature tags (which features are addressed by this model) Instead of coming up with a complicated regexp to jam all this = information into a single version string, we are probably better off = with just having separate qualities in the info block. What we came up with in today=E2=80=99s OneDM meeting: =E2=80=94 put the semver information into the =E2=80=9Cversion=E2=80=9D = quality. To make this comparable lexicographically, we simply use = two-digit numbers (01.02.03). =E2=80=94 add a =E2=80=9Cdate=E2=80=9D quality that can hold an RFC 3339 = full-date or date-time for the point in time when this model was = created/finalized etc., so we have covered this. (This might turn into = multiple qualities if we find that different dates are relevant to a = single model.) =E2=80=94 add an =E2=80=9Ctoken-holder=E2=80=9D quality, which in OneDM = usage would be an (identifier-like) ecosystem name up to the time when a = model is picked up by OneDM. =E2=80=94 add feature tags, which is an (unordered) array of = (identifier-like) text strings that can be used to find out whether a = model addresses a particular feature or not. Info block qualities are a defined extension point in SDF 1.1, so this = should not get us into trouble. (Identifier-like means that the text string is not a sentence, but = something like [a-z][-a-z0-9.]* .) Comments welcome; I=E2=80=99d like to spend a little time discussing = this on Wednesday=E2=80=99s ASDF interim.

On the discussion of PR 28 (htt= ps://github.com/ietf-wg-asdf/SDF/issues/28) in the interim today I promised= write more details about the requirements to the list.

 

For example, I may want to desc= ribe using SDF a sensor device that has an IPSO temperature sensor and an O= CF blood pressure sensor. Both sensors would be ecosystem specific models s= o their definitions come for each ecosystems' namespaces, not from a common namespace. I would like to group both sdfObj= ects in a single sdfThing so simply providing two different definitions wou= ld not work.

 

An earlier draft version of SDF= allowed namespace prefixes for definitions. For example:=

"sdfObject" : {<= /o:p>

"ipso:Temperature" : = { ... },

"ocf:blood.pressure" = : {...}

}

 

However, referring to those wit= h JSON pointer does not work well if you need to expand the CURIE into a fu= ll URI (for example, "#/sdfObject/ipso:Temperature" -> "#= /sdfObject/https://omaspecworks.org/ipso/#Temperature").

 

JSON pointer has escape mechani= sm for '/' (~1) and allows percent-encoding for characters not allowed in f= ragment rule that could help here, but it's admittedly a bit ugly. Can we d= o better / could this work?

 

 

Cheers,

Ari
