Phylogenetics Standards Interest Group or Trees at TDWG Hilmar Lapp & Nico Cellinese

Acknowledgments EOL-BioSynC Mark Westneat, Rick Ree, Audrey Aronowski, and Darolyn Striles National Evolutionary Synthesis Center (NESCent) TDWG organizers for their unbelievable patience, especially Stan Blum for coming to the rescue every time we needed to be rescued Lee Belbin and Anna Weitzman for assistance with our abstract submissions and for putting up with our procrastination

Motivation Consolidate efforts that have been on-going individually or in small groups Build an international platform that helps in broadly promulgating standards and in furthering adoption among stakeholders Interacting with other interest groups facilitates re-use of already existing efforts and standards, and allows harnessing the expertise and experience in developing standards and communicating those to the users

Motivation Combining existing metadata schema, many of which are only implicit. Standardizing the metadata vocabulary and defining common semantics. Addressing interoperability gaps in phyloinformatic tools and web services. Defining data and metadata services, providers, and portals. Defining standards for documenting provenance and relationships between providers.

Motivation Rate of data deposition/ingest into permanent repositories is low and inconsistent. Identifying incentives and standard mechanisms for more consistent data deposition Defining a minimum reporting standard that maximizes the chance of repurposing

Workshop Many people dropped by suggesting that there is a good interest within TDWG about phylogenetic standards development We want anyone interested to join the group We have a TDWG wiki and a mailing list We are in the process of preparing a new EOL- BioSynC proposal to fund additional workshops
