08:41:29 <DaveBrowning> ... In doing this, finding lots of typos, case differences etc
08:41:50 <DaveBrowning> ...suggests that we could improve what exists editorially

08:42:26 <DaveBrowning> SimonCox: If we had proper guidelines previously then that problem would be much less

08:46:46 <DaveBrowning> riccardoAlbertoni: Pulled together a new milestone for quality related information
08:47:25 <DaveBrowning> ...after discussion, made proposal (in github)
08:48:16 <DaveBrowning> ... (describes proposal)
08:50:22 <SimonCox> q?
08:50:25 <SimonCox> q+
08:50:32 <SimonCox> ack SimonCox
08:51:24 <DaveBrowning> SimonCox: Essentially, suggestion is to use existing DQV annotations and predicates as per example in wiki
08:52:03 <DaveBrowning> ... if quality information for a dataset is available then it can be used in the catalogue
08:52:15 <DaveBrowning> ... Where would this info reside?
08:53:07 <DaveBrowning> riccardoAlbertoni: It could be collected in the dataset, unless we need DCAT to be selfcontained
08:55:04 <DaveBrowning> ... connecting the dataset with the dataset with the quality statement is possible but there are challenges.  But there are concerns/other issues
08:55:53 <alejandra> Not following the audio, so sorry if you've already mentioned this, but STAT-DCAT-AP uses DQV and associates the quality to the dataset
08:56:02 <DaveBrowning> ... Proposal as it stands could progress with an new issue raised to cover the outstanding questions
08:56:20 <SimonCox> q+
08:56:22 <alejandra> this is an example from the STAT-DCAT-AP document
08:56:24 <alejandra> <http://qualifications.org/QualityCertificate1> a oa:Annotation. <http://nationalportal.org/data/employment> a dcat:Dataset; dqv:hasQualityAnnotation <http://qualifications.org/QualityCertificate1>. <http://qualifications.org/QualityCertificate1> a dqv:QualityCertificate; oa:hasBody <http://qualifications.org/QualityCertificate1/body>.

08:57:02 <SimonCox> ack SimonCox
08:58:30 <DaveBrowning> SimonCox: This proposal is very in line with the RDF approach, but in the real world there will be non-RDF implementations.  Its that case that I was askling about
08:59:03 <DaveBrowning> ... probably doesn't need to be answered in one place - we could lay out other examples
08:59:11 <DaveBrowning> s/askling/asking
08:59:14 <DaveBrowning> s/askling/asking/
08:59:45 <SimonCox> I think we should at least say something about possible implementation patterns
09:00:06 <DaveBrowning> riccardoAlbertoni: Examples are useful buit clearly are not limiting
09:00:21 <SimonCox> e.g. in-line in blank nodes, or quality statements in the the same catalog, or perhaps in a separate quality service!
09:00:50 <DaveBrowning> s/buit/bit/
09:01:18 <PWinstanley> q+
09:01:24 <DaveBrowning> SimonCox: Obviously makes sense to reuse DQV (probably for PROV as well)
09:02:30 <DaveBrowning> ... but we also need to consider cases e.g. where quality statements come from third parties
09:02:59 <SimonCox> q?
09:03:10 <DaveBrowning> riccardoAlbertoni: Useful to go beyond the linked data perspective
09:03:15 <SimonCox> ack PWinstanley
09:03:23 <SimonCox> q?
09:03:35 <PWinstanley> Platform stability (Average Availability; Mean time to failure; Mean time to repair; Mean time between failure; etc) Platform response (Response time; Throughput; Capacity; ) Scalability (static - add more kit; dynamic; predictive;) Latency Help Desk availability (none; 9-5; 24/7)
09:04:04 <DaveBrowning> PWinstanley: Given we are thinking of dataservices - we maybe need to think about these (above) dimensions?
09:04:58 <DaveBrowning> riccardoAlbertoni: These kind of quality parameters can be supported by DQV (at least that's the intention)
09:05:01 <DaveBrowning> q+
09:05:49 <SimonCox> ack DaveBrowning
09:06:18 <SimonCox> ack DaveBrowning
09:06:37 <PWinstanley> DaveBrowning: I think this is a good approach
09:06:52 <SimonCox> DaveBrowning: riccardoAlbertoni approach looks good in terms of expressivity
09:07:24 <SimonCox> ... as a publisher want to be able to make statement that dataset meets quality policy, metrics
09:07:38 <SimonCox> ... case of third-party assessment is interesting
09:08:06 <SimonCox> ... probably would be in a third place, is not 'part of' the dataset, but is third party annotation
09:08:15 <SimonCox> ... split between consumers and producers
09:09:09 <SimonCox> q+ to note that dqv:QualityMeasurement/dqv:isMeasurementOf should support assement of services as well as datasets
09:10:38 <SimonCox> riccardoAlbertoni: different patterns are possible in architecural design, portal with UI to annotate data? or portal taking inputs from 3rd-party service - use of DQV is neutral
09:10:51 <SimonCox> q?
09:10:56 <SimonCox> ack SimonCox
09:10:56 <Zakim> SimonCox, you wanted to note that dqv:QualityMeasurement/dqv:isMeasurementOf should support assement of services as well as datasets
09:12:19 <SimonCox> PWinstanley: yes, need more examples now we are moving into service description!
09:13:28 <DaveBrowning> SimonCox: Suggests we add some implementation models
09:14:06 <DaveBrowning> ... while reinforcing the use of DQV.  Potentially a few paragraphs that suggest some plausible patterns
09:14:35 <SimonCox> suggest adding some <informative> commentary on implementation options (_not_ recommendations!)
09:15:20 <SimonCox> Good work riccardoAlbertoni - very clear
09:15:36 <DaveBrowning> <general agreement>
09:15:36 <SimonCox> q?
09:16:57 <SimonCox> ACTION: riccardoAlbertoni create issue to write some commentary on possible implementation patterns

09:19:34 <DaveBrowning> SimonCox: Motivation to ensure that people on the same page etc
09:20:34 <DaveBrowning> ... provide some examples.  Then describes requirements/use cases that could utilise this pattern
09:21:16 <DaveBrowning> ... provuides 3 example soultion patterns.   Still a work in progress
