text: The RegCreative jamboree was stimulated by a community initiative to curate in perpetuity the genomic sequences which have been experimentally determined to control gene expression.  This objective is of fundamental importance to evolutionary analysis and translational research as regulatory mechanisms are widely implicated in species-specific adaptation and the etiology of disease.  This initiative culminated in the formation of an international consortium of like-minded scientists dedicated to accomplishing this task.  The RegCreative jamboree was the first opportunity for these groups to meet to be able to accurately assess the current state of knowledge in gene regulation and to begin to develop standards by which to curate regulatory information.
  In total, 44 researchers attended the workshop from 9 different countries and 23 institutions. Funding was also obtained from ENFIN, the BioSapiens Network, FWO Research Foundation, Genome Canada and Genome British Columbia.
  The specific outcomes of the RegCreative meeting to date are:
  * Prior to the RegCreative Jamboree, attendees were asked to participate in an interannotator agreement assessment.  Two ORegAnno mirrors were established with identical sets of publications to be annotated in their queue.  In total, 33 redundant annotations from 18 publications were collected.  (79 annotations for 31 papers and 60 annotations for 21 papers were collected on servers 1 and 2, respectively.)  This effort was used as a baseline from which to establish annotator efficiency.
  * Hands-on annotation activities occurred during the first 2 days of the 3-day workshop.  In total, 39 researchers contributed 184 TFBS and 317 Regulatory Regions from 96 papers.  Many of these researchers were also trained on the ORegAnno system, significantly increasing its experienced-user community.  The contribution of these annotations to individual species was 339 annotations in Homo sapiens, 42 annotations in Mus musculus, 72 annotations in Drosophila melanogaster, 24 annotations in Ciona intestinalis, 14 annotations in Rattus norvegicus, 6 annotations in Halocynthia roretzi, 2 annotations in Ciona savignyi and 2 annotations in HIV.  Within these annotations, one new dataset was added to ORegAnno; 274 human enhancers were programmatically annotated by Maximillian Haessler, Institute Alfred Fessard, from Visel et al., Nucleic Acids Research, 2006.  In total, 130 scientific studies were examined in depth.   The annotated papers were pre-selected from expert-curated publications in the ORegAnno queue that had full-text available through HighWire Press.
  * There exists an immediate need for improved data standardization and development of associated ontologies.  Specifically, this should include the open access development and integration of transcription factor naming conventions and sequence, cell type, cell line, tissue, and evidence ontologies.  The groundwork for addressing and prioritizing these needs was accomplished in several ways during the meeting:
  **  Transcription factor naming issues were addressed through discussion of integration of transcription factor prediction pipelines, such as DBD or flyTF, which have been supplemented with manual curation versus solely manual curated implementations like TFcat.
  ** [http://www.ccr.buffalo.edu/halfon Marc Halfon], University at Buffalo, led a breakout session to improve the [http://song.sourceforge.net/ Sequence Ontology] from existing ORegAnno and REDfly database conventions within the framework being developed as part of the Open Biomedical Ontologies.  A preliminary version of these improvements can be found on the [http://www.bcgsc.ca/wiki/display/oreganno/SeqOntology ORegAnno wiki].
  ** Learning-based ontology development was widely regarded as an essential feature of the annotation process.  Such that, annotators are not restricted from annotating based on the limitations of the controlled vocabulary and that these exceptions can be used to further develop the backbone ontologies.
  ** Ontology development should be decentralized from the ORegAnno annotation framework.  Specifically, it is planned that the ORegAnno evidence ontology will be removed and made available to broader community development.
  ** Renewed focus on integrating species-specific resources with annotation framework.
  * A specific focus of the workshop was addressing the role of text mining in facilitating regulatory annotation.  Sessions were led by Dr. Lynette Hirschman, MITRE, and Dr. Martin Krallinger, CNIO, to formulate where text-mining can help.  A short term object of text-mining based analyses was formulated around both populating the ORegAnno queue and using the expert-curated portion of the ORegAnno queue to validate text-mining-based publication acquisition.  The latter objectives are being led by Dr. Stein Aerts, University of Leuven.
