We currently have 25 photographers using their own cameras and I am not sure how we would be able to determine and/or document magnification levels without the use of a scale. If we were working with a single make and model of a camera attached to a microscope I think the issue of magnification of the raw image would be easier to determine.

AC Comment: terms for phylocode and DNA barcode
by Steve Baskauf 25 Mar '13

25 Mar '13

Rob Stevenson made another helpful comment with regards to the proposed Audubon Core standard: "Rather than have Term Name: associatedSpecimenReference as a place for phylocode and a DNA barcode, should the standard support specific fields for a phylocode and a DNA barcode? These seem to be independent approaches that might help anchor or tie together multimedia observations. I can image people taking a picture of an insect and getting a DNA barcode but not having a Taxon Name or a set of characters completed. It seems that molecular data are becoming more and more important and their collection is becoming more and more automated. For microbes, molecular characterization seems to be the main approach uses". I have not opened an issue for this item because although it is an important issue, I'm not sure it is in scope for Audubon Core. AC imports terms from other vocabularies when possible (notably Darwin Core), but generally only mints terms when they deal specifically with multimedia and when existing vocabularies don't already provide such a term. The issue that Rob raises is a general one that needs to be discussed in the context of how vocabularies such as Darwin Core (which are currently designed primarily to facilitate "flat", specimen-oriented databases) can be adapted for use in more normalized databases which integrate information about many kinds of resources (e.g. specimens, DNA sequences, images, etc. ). This is a topic that is the subject of ongoing discussions with groups such as BiSciCol, RCN4GSC, and the TDWG RDF task group. But it may be too much for Audubon Core to take on at this point in time. Opinions? Steve -- Steven J.

AC Comment: opened new issues
by Steve Baskauf 25 Mar '13

25 Mar '13

Rob Stevenson has provided several useful comments regarding the proposed Audubon Core standard. I have opened two issues related to his comments: Issue 45 (http://code.google.com/p/auduboncore/issues/detail?id=45 ) to include LTER Datasets controlled vocabulary for CVterm term. Issue 46 (http://code.google.com/p/auduboncore/issues/detail?id=46 ) which combines Alexey Zinovjev's earlier comment with a comment from Rob regarding specifying multiple taxa related to a media item: "Let's say I have a picture of a leaf with holes in it. Is there a way to specify the taxon of the leaf and the taxon of the insect that made the holes. Caterpillar species A eats Plant leaf Species B? If I know that caterpillar only made that shape hole when it was parasitized can I also specify the taxon of the parasite? Another leaf example would be lichens and liverworts that colonize leaves. One might be over growing another? In general I would like to specific multiple taxa and relationships among the taxa in the image or movie, etc" Steve -- Steven J.

Audubon Core Review: media recording traces of organisms
by Steve Baskauf 24 Mar '13

24 Mar '13

Here is a forward of a question I received regarding the Audubon Core term list: The immediate question: How would I record most of my sawfly photos: which are usually not sawflies [adults or larvae] themselves but their galls, mines, 'holes in leaves' (sometimes, by their shape, I can precisely identify species produced it), etc., etc. People will photograph nests, animal's traces, record bird songs, but how such media would be tracked? It seems to be a very common situation. I did not notice anything for such "product" instead of animal itself. I should have seen a generic term somewhere but don't remember neither the English or Latin word nor where could I see it. Alexey -- azinovjev(a)fastmail.fm

Review of TDWG ontologies and DwC namespace policy
by Steve Baskauf 13 Mar '13

13 Mar '13

The Vocabulary Management task group (VoMaG) is soliciting input for a report with recommendations for future action on the part of TDWG. I have been co-opted to organize contributions to the report on the topic of the status of the TDWG ontologies and a review of the Darwin Core namespace policy. In particular, what (if anything) should be done with the TDWG ontologies and should the Darwin Core namespace policy (i.e. the mechanism for amending Darwin Core) be adopted in some form as a model for all TDWG voabularies? If you have opinions or suggestions that you would like to contribute, you can do so at the VoMaG site. The task group entry page is at: http://community.gbif.org/pg/pages/view/30603/ The background summary on the TDWG ontologies and DwC namespace policy is at: http://community.gbif.org/pg/pages/view/29079/ which has a link to the page for discussion. If you find the wiki format to be a barrier, you can also email comments directly to me. The timeline for moving the report forward has a March 31 deadline for contributions, so if you have thoughts on the subject, please assemble them by the end of the month.

Audubon Core Public Review
by Steve Baskauf 02 Mar '13

02 Mar '13

(Apologies for any cross-listing) Audubon Core Public Review By: Steve Baskauf, Review Manager Biodiversity Information Standards (TDWG) announces the Public Review of the proposed Audubon Core Multimedia Resources Metadata Standard. Audubon Core is designed to provide a controlled vocabulary to address the management, acquisition, and content descriptions of biodiversity multimedia. It is a product of the Joint GBIF- TDWG Multimedia Resources Task Group (MRTG) and has undergone peer review, several revisions, and review by the TDWG Executive Committee. If you are a potential producer or consumer of metadata for biodiversity-related multimedia, we would like your input on this proposed TDWG Technical Specification Standard. You may find it easiest to view the proposed standard online. The following links lead to the three parts of the standard: - the non-normative introduction: http://terms.gbif.org/wiki/Audubon_Core_Non_Normative_Document - the normative introductory material: http://terms.gbif.org/wiki/Audubon_Core_(1.0_normative) - the normative term list: http://terms.gbif.org/wiki/Audubon_Core_Term_List_(1.0_normative) A downloadable zip archive containing the proposed standard can be obtained at http://www.tdwg.org/standards/638/ . This archive includes an informative adoption and sustainability plan which is not an official part of the proposed standard. To raise specific issues or to make specific recommendations, use the issues tracker described at http://code.google.com/p/auduboncore/wiki/AboutIssueTracker . To engage in general discussion about the standard, join the TDWG email list (tdwg-content) by subscribing at http://lists.tdwg.org/mailman/listinfo/tdwg-content . You can then post messages to tdwg-content(a)lists.tdwg.org . Issues raised in that conversation may be added to the issue tracker as well. Comments about the proposed standard will be archived as a part of the standards adoption process. In accordance with the TDWG standards process, a minimum of 30 days is required for public comment on the proposed standard. Comments should therefore be received by 1st April 2013. For more information about the TDWG standards process, see http://www.tdwg.org/standards/status-and-categories/ and http://www.tdwg.org/about-tdwg/process/ .

Open Annotation Ontology Rollout
by Bob Morris 15 Feb '13

15 Feb '13

The W3C Open Annotation Community Group <http://www.w3.org/community/openannotation/> is pleased to announce three public meetings introducing the Open Annotation Data Model Community Specification. The Open Annotation Core Data Model <http://www.openannotation.org/spec/core/> specifies an interoperable framework for creating associations between related resources, annotations, using a methodology that conforms to the Architecture of the World Wide Web. Open Annotations can easily be shared between platforms, with sufficient richness of expression to satisfy complex requirements while remaining simple enough to also allow for the most common use cases, such as attaching a piece of text to a single web resource. These day-long public roll-outs, carried out in concert with the Annotation Ontology and the Open Annotation Collaboration, and made possible by generous funding from the Andrew W. Mellon Foundation, will inform digital humanities and sciences computing developers, curators of digital collections and scholars using digital content about the W3C Open Annotation Community Group’s work. Participants will learn about the data model's core features and advanced modules through tutorials, a showcase of existing implementations, Q&A sessions with community implementers and live demonstrations. Topics will include: * The Open Annotation Data Model * The W3C Open Annotation Community Group * Existing implementations * Developer tools & resources Rollout times and locations: * U.S. West Coast Rollout – 09 April 2013 at Stanford University Registration: <https://www.eventville.com/Catalog/EventRegistration1.asp?Eventid=1010270> * U.S. East Coast Rollout – 06 May 2013 at the University of Maryland Registration: <https://www.eventville.com/Catalog/EventRegistration1.asp?Eventid=1010271> * U.K. Rollout – 24 June 2013 at the University of Manchester Registration: <https://www.eventville.com/Catalog/EventRegistration1.asp?Eventid=1010272) There is no registration fee but RSVP (online) is required. RSVP for a rollout near you using one of the links above. For more information and individual agendas, see: <http://www.openannotation.org/RolloutInfo.html> -- Robert A.

Hi Everyone, Are you interested in digitization workflows for natural history museum collections that involve OCR, machine learning and natural language processing? iDigBio's first Hackathon starts this morning, Wednesday February 13th and begins with 10 minute lightning talks by participants sharing their results so far to parse OCR output. Participants will spend 2 days together sharing and tweaking algorithms aimed at making parsing OCR output better. Other big topics of the hackathon are image processing/segmentation/analysis and also the continued need for user-interface development for interacting with the OCR output (front-end human-in-the-loop and api interfaces). Tune in: http://idigbio.adobeconnect.com/augmentocr 9AM - to about noon CST. Read more at: http://tinyurl.com/aocrhackathonwiki Works better with Firefox (b/c of Flash). Headsets are a good idea for best sound. From all of us at the Hackathon, See you there. Deb
