publication schedule (from last week)

<DaveBrowning> acl alejandra

DaveBrowning: is there a consensus about abour goal?

alejandra: we aim for rec by June, need to submit by mid April, need to be ready by mid March

<riccardoAlbertoni> yes we were targeting mid march

DaveBrowning: are there any tasks prioritized?

DaveBrowning: e.g. statements about security, namespace page .. what else?

DaveBrowning: any cricital issues?

alejandra: looking at milestone 3rd public WD, e.g. versioning, other issues under discussion + editorial ones

open action items

<DaveBrowning> https://‌www.w3.org/‌2017/‌dxwg/‌track/‌actions/‌open

DaveBrowning: hard to estimate without Peter & Andrea being here

alejandra: move on, no substantial progress

planning and organisation

alejandra: sprint planning

riccardoAlbertoni: I worked this week on Andrea's summary of DCAT 2.0 implementations adding LusTRE example
… could we invite other parties / working groups to augment?

alejandra: we should call to people that may provide implementations ..

<riccardoAlbertoni> I can

DaveBrowning: anybody to draft such an invitation email?
… will not work, I'll remember my action, there are organisational problems..

DaveBrowning: back to sprint planning: sprint next week on implementation?
… but it might be tough because of the short time remaining

closing github issues

<DaveBrowning> https://‌github.com/‌w3c/‌dxwg/‌issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aopen+label%3A%22due+for+closing%22+label%3A%22dcat%22

DaveBrowning: this one surprised me:

<DaveBrowning> Ids this issue ready? https://‌github.com/‌w3c/‌dxwg/‌issues/‌411

DaveBrowning: what is the status?

alejandra: we've agreed on Annett's proposal to collect examples

alejandra: it's more about relation of distributions..

SimonCox: at the end it is a decision of the publisher, a general solution maight be a profile

<SimonCox> For more esoteric properties, a provider might define extensions in a DCAT profile

DaveBrowning: decision on #411 - it should be closed, like those 6 listed

<DaveBrowning> proposal: to close all of the DCAT issues currently in 'due for closing'

alejandra: I did not look at all of them, we may close those, that are resolved, otherwise we should mark "wan't fix"

<DaveBrowning> proposal: to close all of the DCAT issues currently in 'due for closing', marking as wontfix if appropriate

<riccardoAlbertoni> +1

<SimonCox> +1

DaveBrowning: is the silence indicating approval, or?

<DaveBrowning> proposal: to close all of the DCAT issues currently in 'due for closing', marking as wontfix if appropriate

<alejandra> +1

+0 (can't say at moment)

Resolved: to close all of the DCAT issues currently in 'due for closing', marking as wontfix if appropriate

rrsagent: draft minutes v2

implementation evidence

alejandra: we discussed last week, Andrea created the sheet, Riccardo will create the email, please vote on the doodle poll

open pull requests

pull requests

<DaveBrowning> https://‌github.com/‌w3c/‌dxwg/‌pull/‌741

DaveBrowning: should we talk about this (e.g. ordering of contributors)?

riccardoAlbertoni: me should not be the first one (because of alphabet)

DaveBrowning: hard to give a (different) ordering

DaveBrowning: should look at other substantial pull requests, will park this

<DaveBrowning> https://‌github.com/‌w3c/‌dxwg/‌pull/‌776

<DaveBrowning> https://‌github.com/‌w3c/‌dxwg/‌pull/‌777

SimonCox: almost ready on spatial resolution (#777)

SimonCox: still working on other issues as well

alejandra: thanks to SimonCox for helping out here

alejandra: the original UC I submitted was about a way to represent / link a "summary statistics"

DaveBrowning: we should give such relevant measures/sizes etc.

<alejandra> examples that my use cases was considering is knowing statistics about the data, which would be specific for a domain, such as number of patients

SimonCox: which (else) type of statistics were required?

alejandra: this probably may be solved by Data Cube structures (or void), depending on the domain

<SimonCox> and also temporalResolution is now ready as well (#776)

<SimonCox> I worked on temporal- and spatial-resolution because (a) they could be solved relatively easily (!) with some discrete additions (b) they address important requirements (late-arriving from Dagstuhl workshop)

Jaroslav_Pullmann: which types of statistics?

alejandra: both: on Distributions (extrinsic) and data subjects (intrinsic)

alejandra: we should make a proposal to accept the predicates suggested by SimonCox

<DaveBrowning> proposal: accept the changes in pull requests #776 and #777 (pending final review of detail)

+1

<SimonCox> +1

<DaveBrowning> +1

SimonCox: reporting on both predicates

<SimonCox> this relates to additional predicates (i) dcat:temporalResolution (ii) dcat:spatialResolutionInMetres

<alejandra> +1

<riccardoAlbertoni> +1

SimonCox: these are straight forward datatype properties with simple XSD datatypes (duration, decimal)

<DaveBrowning> resolved accept the changes in pull requests #776 and #777 (pending final review of detail)

Resolved: accept the changes in pull requests #776 and #777 (pending final review of detail)

<SimonCox> ... by editors

<SimonCox> rrsagent: draft minutes v2

<alejandra> https://‌www.standict.eu/‌OpenCalls/‌5th-Open-Call
