Conference Call to Begin On-line Polling on Standards

Agenda

• Introduction and goals• Brief overview of DMAC standards

process• Focus on polling

– Standards under review– Schedule/due dates– Review of bylaws/voting issues

• Next steps• Open discussion

Introductions

• Welcome – Mary Altalo, Anne Ball• “Roll call” – DMAC members• Introduction of guests

– Capt. Chris Moore, NOAA IOOS Program• Funding and oversight of DMAC standards website

– Delta Pelgrim, LMI• Technical support and gatekeeper for website

– Kurt Schnebele, LMI• Former DMAC Chair• Standards process and website support

Goals

• Kick-off polling component of DMAC standards process to ensure steering team members:– Understand process– Know what is expected of them– Are aware of schedule and due dates

DMAC Standards Adoption Process

Brief overview

• Process was approved at May 2006 Steering Team meeting – (see

IOOS-DMAC Guidelines/Standards Adoption process)

• NOAA IOOS Program provided funding and oversight to implement website through LMI

DMAC Standards Adoption Process

Brief overview (continued)

Three status levels for standards:• Submitted

– Has no standing within IOOS.

• Proposed– Has status within IOOS and can be used provisionally by IOOS

information system managers for evaluation purposes.

• Recommended– All IOOS data systems should consider supporting these

guidelines wherever applicable

Polling

Points to remember:

• Private mechanism for on-line polling (not visible to anyone outside the Steering Team)

• Threaded discussions available to discuss individual standards

Possible Recommendations

Steering team may decide the following on the standards:

• Move forward (“submitted” to “proposed”)

• Request additions or changes

• Table and revisit in next round

• Reject

After the ‘Polling’submitted - to - proposed

• Chair will write up draft recommendations based on polling and distribute to Steering Team

• Steering Team will discuss recommendations at Dec 17 conference call– Members can designate alternate to attend and vote– Try to reach consensus– If consensus is not possible:

• Vote is carried by 75% of those members voting “approve” or “disapprove.”

• Quorum consists of 60% of members.• Support of multiple strategies may be the most prudent approach.

As long as the consideration of multiple options does not violate the spirit of IOOS interoperability, the IOOS-ST may move forward without consensus.

– (see DMAC Steering Team Terms of Reference)

Standards for review

Eight standards:

• IOOS Vocabulary Version 1 • Required and Recommended Vocabularies for IOOS Metadata • Metadata Catalog Services • Data Access Protocol – DAP 2.0 (transport) • Real Time Quality Control Tests for In Situ Ocean Surface Waves • Quality Control Standards for Real-Time, In Situ Currents

Measured by Teledyne RD Instruments • High Frequency Radar Surface Currents • Standards Package for the Representation and Transport of

Gridded Data: netCDF+CF+OPeNDAP+aggregation
