2) Hack-a-thon prep 
3) Data Quality (Ted) 

Summer Meeting Sessions:

Google Doc:

5 sessions have been identified as Documentation (in yellow).  (Data stewardship are in pink)

1)      Steve Richard – Information exchanges and interoperability architecture (Wed 4 – 5:30)

2)      Katie Baynes – Streamlining Metadta using the CMR (ECHO and ESIP) (Thurs 9-1030)

3)      Barry Weiss – Design and Implementation of ISO Metadta in Science Data Products

4)      Ge Peng – Identifying and Assessing Best Practices in Data Quality

5)      Anna Milan - <MD_HackAThon>

4) 2 talk on quality a 1Hr discussion (Peng) – possibly include talks by Ted, Ed, and Alek)

3) Berry and Jeff Lee – OCDD

Ted is not sure about what will be included in 1 and 2


MD_HackAThon - Anna

·         See is as 2 things – a way to address problems with MD and how to apply ISO to special data sets

·         Do we want to recommend a tool set?  If so oXygen (has 1 month free trail)

·         Peng – it is metadata or other – Archieve, Data Quality, seach/distribution

·         Ed – maybe take model from satellite mission and see hhow best ot encapsulate in ISO  a single GRIST granule

·         Anna – have people volunteer problems before the meeting

·         Use 19157 and 19115-2 (not 19115 or 19115-1)

·         Peng – Data quality could use more guidance

·         Anna – should we split into 2 groups – how to use tool and problems or just pick 1

·         Ted have about 10 things (lineage, acquisition, resources, etc) have have people vote on what they want to see (on a wiki page)

o   Kelly – might want to use survey monkey or survey gismo

·         Anna – people’s data are special and want to help them – also ask about learning tools in the survey


·         Anna – will other sessions cover – yup – Tuesday US Geo


·         Ed – what is the difference between Data Stewardships’ and Peng’s data quality sessions

o   Peng’s focuses more on best practices in DQ – intro maturity matrix

o   Data Stewardships’ has 2 invited talks and a discussion

ISO 19157 – A framework for Progress on Data Quality

·         Data quality moved from ISO 19115 (black) to 19157 (red) (colors are for Ted’s presentation)

·         It is currently an approved concept model – will be edited in June and then become an international technical specification

·         Elements are abstract (triangle) means can be implemented in different ways

·         Data Quality has elements

o   Three parts – measure, evaluation method, results

o   Has a standalone quality report

·         Scope – defined range or elements for a quality set or result

o   Can have quality for subsets

1)      Done with scopecode – text term (has list of valid elements)

2)      Extent – geographic, temporal, spatiotemporal, or vertical

3)      Scope description – what attribute/feature quality applies to

·         Standalone quality reports are new – link a citation to a report (possibly a journal article)

·         Modular quality information

·         Measure to database – each group builds database

·         There are many types of reports – did not change from 19115

o   Data quality usability (191152) – usability implied elements of data quality

·         Data Quality Evaluation Methods

o   Direct internal = use data in data to evaluate

o   Direct external – between dataset

o   3 types of results (include time and scape for each result)

1)      Quantitative

2)      Conformance

3)      Converge

4)      Descriptive (NEW)

·         Metaquality – quality of quality information

o   Way each was applied – homogeneity, confidence, representatively

·         Peng – what happens to issues of data quality identified after the data is released

o   Reports include dat and time – can querry reports for specific times/data and elements

o   Ex. SEDAC (socioeconomic data and application center) – has a feedback system for their data

·         Peng – challenge is who will implement

·         Anna – what about content, quality, and lineage –these are often overlooked
