Issue: Adding Semantic Annotations to JSON Schema
06:45:03 [trackbot]
Created ISSUE-1 - Adding semantic annotations to json schema. Please complete additional details at <>.
06:45:23 [DarkoAnicic]
06:46:04 [kaz]
i|Open Action|[ minutes from Apr. 26 TD model call have been updated: ]|
06:46:26 [DarkoAnicic]
Victor: we introduced the issue, use case, someone already gave a proposal
06:49:22 [DarkoAnicic]
Victor: the example shows the issue when within the schema the structure of two semantically described items cannot be differentiated.
06:50:24 [DarkoAnicic]
Victor: thus we need the semantic annotation to to JSON Schema
06:51:31 [kaz]
i|Adding Semantic|-> Issue 309|
06:51:31 [DarkoAnicic]
McCool: the context in JSON cannot be added in the same fashion as in JSON-LD

McCool: we should have a TD schema, describing the class, and the TD, describing an instance thereof

no, I was in the queu for the minutes thing, how do I remove that?

present+ Zoltan_Kis
06:58:45 [DarkoAnicic]
McCool: do we have one schema for all kind of Things?
06:59:55 [DarkoAnicic]
Victor: everybody can add or extend the TD vocabulary if we rely on Semantic Web technology
07:00:47 [DarkoAnicic]
Sebastian: let us keep the JSON as it is. We want to add semantic annotations only.
07:01:30 [DarkoAnicic]
s/JSON/JSON Schema
07:02:14 [DarkoAnicic]
Sebastian: we define Events, Properties, Actions in TD and rely on JSON Schema for Data Types
07:03:57 [DarkoAnicic]
McCool: we have to define vocabulary in advance to enable contained IoT device to handle them. But for different domains/devices we need multiple schema - this complicates things.
07:04:21 [kaz]
07:04:33 [DarkoAnicic]
Victor: in addition two devices may use different vocabularies even for the same domain.

07:05:40 [DarkoAnicic]
Victor: we should not enforce one schema/one structure only, need to be flexible.
07:06:21 [kaz]
07:06:35 [DarkoAnicic]
McCool: I suggest we stich to JSON as the mapping to other formats can be made.
07:09:00 [DarkoAnicic]
Sebastian: this will be one of the major topics in the upcoming F2F meeting in Osaka. Please follow and contribute.

Action: kaz to create an issue about two-way approach: device dependent and non-depend path
07:12:10 [trackbot]
Created ACTION-104 - Create an issue about two-way approach: device dependent and non-depend path [on Kazuyuki Ashimura - due 2017-05-12].
07:12:10 [kaz]

McCool: for the ns we need the year/month etc.
07:13:16 [DarkoAnicic]
Sebastian: Dave already registered the ns without the date
07:13:55 [DarkoAnicic]
kaz: we can add a shot name, e.g., wot-td
07:13:56 [MariaPoveda]
It is not an exception see
07:14:55 [DarkoAnicic]
McCool: the version of the vocabulary is needed to avoid errors
07:15:05 [kaz]
s/we can add a shot name, e.g., wot-td/another option could be using the shortname for TD, e.g., "wot-thing-description"/
07:15:33 [DarkoAnicic]
Maria: are you referring to the version of the vocabulary of documents that will be published
07:15:38 [McCool]
07:16:54 [DarkoAnicic]
Maria: the name space without date points always to the last (actual) vocabulary, wheres the previous versions are pointed with links with dates
07:17:08 [McCool]
07:17:18 [McCool]
07:18:57 [DarkoAnicic]
kaz: we use wot-thing-description for the Git and the same can be used also as ns
07:19:26 [DarkoAnicic]
Sebastian: the issue is not that urgent but we should resolve it in communication with Dave

Sebastian: we have 2 versions of the TD model: one more for web developers and another, more suited for Semantic Web community. We may have both versions.
07:22:11 [kaz]
s/reuse that shortname for the namespace/reuse that shortname for the namespace. probably that would be less confusing./

07:26:32 [DarkoAnicic]
