propose to accept minutes of last week's telco

resolved

<emma> RESOLVED: To accept http://www.w3.org/2005/Incubator/lld/minutes/2011/01/06-lld-minutes.html

Tom: start with report from Karen

Report from ALA Mid-Winter and LITA/ALCTS actions

2nd time held a meeting at NALA

included people from LOC

enough signatures to turn it into an official ALA interest group. will be in the program, meet twice a year

kcoyle: did gap analysis. will establish a discussion area, post it online

<digikim> lol, data speeddating :)

kcoyle: came up with the idea for "data speed-dating" events

<emma> +1 for data speed-dating ;-)

<digikim> +1

kcoyle: there's interest in developing LLD
... people surprised we received no use cases re traditional library data (re MARC, RDA, ...)
... a lack of the way for to move what we have today into linked data
... wrote 2 reports: on SemWeb (award for best report) and on RDA

congrats! :)

<GordonD> I can add a use-case for migrating from legacy records (MARC, etc.) to the BibData cluster

scribe: will we do something re traditional library data?
... will send a link for a report from the meeting.

<antoine> http://www.w3.org/2005/Incubator/lld/wiki/Vocabularies

antoine: asking about lack of traditional library data use cases. RDA is mentioned in ~3 use cases.

kcoyle: will look into it.

<GordonD> I think we need something specific about legacy data and migrating to lld

kcoyle: i think what people expected was a use case about that

<rsinger> formally?

TomB: can we add an action re this?

<GordonD> I've already volunteered

<rsinger> yeah, i'll definitely volunteer

<jodi> Gordan++

<GordonD> Yes, please action this to me

<scribe> ACTION: Gordon and Ross to review use cases in light of migration of legacy data [recorded in http://www.w3.org/2011/01/13-lld-minutes.html#action01]

<GordonD> Tom - you missed out the Collections cluster

Use Cases

<scribe> ACTION: TomB to link cluster pages to http://www.w3.org/2005/Incubator/lld/wiki/FinalReportOutline -- done [recorded in http://www.w3.org/2011/01/13-lld-minutes.html#action02][DONE]

<marcia> we have a UC http://www.w3.org/2005/Incubator/lld/wiki/Use_Case_Linked_Data_and_legacy_library_applications

<marcia> a UC by uldis

TomB: vocabulary alignment
... onging action by Antoine and Michael
... main topic for this week

<TomB> ACTION: Antoine and Michael to curate vocabulary alignment cluster for end of December [recorded in http://www.w3.org/2005/Incubator/lld/minutes/2010/10/23-lld-minutes.html#action07] [CONTINUES]

antoine: vocabulary alignment cluster joined by Marcia who contributed
... cluster motivation: many institutions have specific vocabs to describe their collections
... different metadata schemas
... various thesauri, classification systems
... causes problems for managing that data. objective: to solve the problem of access to collections by end-users.
... use cases where users want to access multiple collections, via unified access points.
... examples: Europeana, other integrated search services
... need to relate these vocabularies
... applies both to search and exploring collections
... also has metadata management scenarios. for creating new vocabularies or matching existing vocabs.
... one specific cases concerned with that
... match between these motivations and the linked data

<Zakim> TomB, you wanted to ask whether "alignment" should include also element sets and datasets

TomB: cluster is defined about vocabulary alignment, but noted in text it is also true for metadata elem set alignment
... is alignment of data sets also covered here (or somewhere else?)

<marcia> Tom: do you mean to change to 'alignment' regardless of if it is on the vocabulary level or value level?

antoine: both alignment of vocabs and element sets.
... don't have use cases that talk about data sets

<rsinger> Sorry, everybody, need to bow out for another meeting.

antoine: received a number of case studies in this cluster

<GordonD> The BibData has a de-duplication use-case, but it is at record level, not lld

antoine: identified other cases relevant to the cluster

<antoine> http://www.w3.org/2005/Incubator/lld/wiki/Cluster_VocAlign_RelevantCases

antoine: collected in this link all the cases from cluster which are relevant. some could be about data sets.

<Zakim> emma, you wanted to talk about similarities with Archives

emma: in archives cluster one of main topics of interest: archives want to relate their objects with one another
... aligning value vocabularies. similar to this cluster.

<Zakim> TomB, you wanted to suggest analytical approach to "relevant technologies"

michaelp: looking at relevant technologies for merging vocabularies. need analytic view to various approaches.
... have links to various services, frameworks.
... ... by technical approaches - how they are making and publishing mappings

<Zakim> michaelp, you wanted to mention problems with defining data set alignment

michaelp: should be careful with what we define as aligning data sets and vocabularies
... there's big overlap. very real issue.
... but in vocab alignment you establish more semantic relationships. there similarity with data sets ends.

TomB: also an issue with provenance information (in the notes)
... Marcia, Antoine: what further input is needed on this call or on the list
... how close are to having the action done and having a draft?

<marcia> We have two cases seemed to belong to other clusters

antoine: would like to have input re selection of cases
... problem: have 2 cases where did not see a link with vocab alignment
... subject search
... component vocabularies
... if could have input from people who created them
... worked on stabilizing scenarios
... concept-based search; mediation between vocabs; vocab emerging
... also relation to an interesting use case for natural language processing

scribe: trying to organize and validate the problems section

<marcia> maybe we can also summarize the types of alignment 'parties'.

TomB: please post a message to curators of use cases (re cases where don't see a link)

<marcia> +Antoine. Great report.

CLUSTER Archives and heterogeneous data

<kcoyle> done

<scribe> ACTION: Kcoyle to see if Archives cluster reveals problems or limitations -- things missing from the available technology that would make LLD implementable [DONE] [recorded in http://www.w3.org/2011/01/13-lld-minutes.html#action04]

kcoyle: action completed, sent to the list

<jodi> http://www.w3.org/2005/Incubator/lld/wiki/index.php?title=Cluster_VocAlign&oldid=2627#Problems_and_limitations

<TomB> http://lists.w3.org/Archives/Public/public-xg-lld/2011Jan/0034.html

kcoyle: other cluster has those. suggest that all clusters see what gaps, problems are there and send to Karen
... Karen can put them together

<marcia> Karen: Antoine organized those gaps according to your category/outline. http://www.w3.org/2005/Incubator/lld/wiki/Cluster_VocAlign

TomB: so that we have something comparable between clusters.

TomB: should assume actions carried forward?

<GordonD> +1

<emma> ok

TomB: yes

kcoyle: will join the cluster

<scribe> ACTION: GordonD to curate collection cluster [recorded in http://www.w3.org/2005/Incubator/lld/minutes/2011/01/06-lld-minutes.html#action11][CONTINUES]

INDIVIDUAL USE CASES

TomB: an action for each use case curator

<antoine>

<scribe> ACTION: For each use case curator: on the Vocabularies page (http://www.w3.org/2005/Incubator/lld/wiki/Vocabularies) link to each URL use case that uses it [recorded in http://www.w3.org/2005/Incubator/lld/minutes/2010/10/23-lld-minutes.html#action01] does it need to be continued?

<emma> I just added the Collections Cluster page to the final report outline

UNKNOWN_SPEAKER: do we need to link each use case that uses particular vocab to the vocab page?
... or can the action be dropped.

<kcoyle> i'm not clear what the purpose is... i also think it could be considered done

antoine: action is done

<GordonD> Generally, any new use cases added need to remember to update terminologies/vocabularies/links, etc.

<marcia> + Gordon

<kcoyle> no list will be complete -- this is good enough

TomB: decided to drop the action

<scribe> ACTION: For each use case curator: on the Vocabularies page (http://www.w3.org/2005/Incubator/lld/wiki/Vocabularies) link to each URL use case that uses it [recorded in http://www.w3.org/2005/Incubator/lld/minutes/2010/10/23-lld-minutes.html#action01] [DONE]

TomB: end of today's agenda. any other comments?
... topic next week = bibliographic data

<jeff_> http://lists.w3.org/Archives/Public/public-xg-lld/2011Jan/0037.html

jeff_: has an action that's done

<scribe> ACTION: Jeff to write one or two paragraphs on VIAF design discussions as per http://lists.w3.org/Archives/Public/public-lld/2010Oct/0107.html[recorded in http://www.w3.org/2010/11/18-lld-minutes.html#action06] [DONE]

<scribe> --done

TomB: thought that design discussion also talked re relation b/w authority data and real-world objects
... this issue needs to be covered (but can be covered in the authority data cluster)

... this was telco #24
... we have 15-20 telcos left
... no concrete plans for F2F. we're in good shape, clusters are looking good.

<scribe> ... finished for the week

<kcoyle> uldis - great job!

<michaelp> Thanks!

kcoyle - cheers! :)

<emma> thanks Uldis :-)

<marcia> uldis , great
