<p>After an extensive period of community feedback and testing, the <a href="https://www.tdwg.org/community/dwc/">Darwin Core Maintenance Group</a> has approved moving the proposal for a <a href="https://gbif.github.io/dwc-dp/">conceptual model and Data Package guide</a> forward to a period of public comment. The public comment period will begin on Wednesday, 17 September 2025 and will extend until at least 16 December (90 days).</p>

<p>This public review is longer than normal since this coordinated set of additions and changes to the Darwin Core standard is more complex than typical change proposals. The procedures for handling such complex proposals, known as vocabulary enhancements, are described in the <a href="http://rs.tdwg.org/vms/doc/specification/#4-vocabulary-enhancements">TDWG Vocabulary Maintenance Specification</a>. In deciding to move the proposal forward, the Maintenance Group considered the working group’s Implementation Experience Report to assess the necessity and effectiveness of the proposed changes relative to needs expressed by members of the community who chose to participate in the initial development and testing of use cases.</p>

<p>A link to this report, along with summary descriptions of and links to details of the three major parts of the proposal, are included in a review landing page at <a href="https://gbif.github.io/dwc-dp/">https://gbif.github.io/dwc-dp/</a>. The landing page also explains how you can participate in the review. All members of the community are encouraged to participate. We would particularly welcome feedback from those with technical expertise and interest in developing applications based on the Conceptual Model and Data Package guide, included in the proposal.</p>

<p>If you have any questions about the review, please contact <a href="mailto:steve.baskauf@gmail.com">Steve Baskauf</a>.</p>

<p>TDWG is pleased to announce the signing of a Memorandum of Understanding (MoU) with the International Commission on Zoological Nomenclature (ICZN). This agreement marks a significant step toward closer collaboration in promoting biodiversity data standards and the integration of zoological nomenclature into global informatics efforts.</p>

<p>The partnership underscores our shared commitment to advancing open science, ensuring interoperability, and supporting the long-term accessibility and usability of taxonomic information.</p>

<p>We look forward to working together with ICZN to strengthen the foundation of biodiversity data worldwide.</p>

<h3 id="remarks">Remarks</h3>

<p><em>“Scientific nomenclature aims to bring clear and unambiguous data-sharing and communication about species, and strengthening the ICZN-TDWG axis would seem a win-win situation in a time where ‘big data initiatives’ are increasingly important for safeguarding and managing our ecosystems.”</em>  (<strong>Thomas Pape, President, ICZN</strong>)</p>

<p><em>“Scientific nomenclature is the informatics backbone underpinning all of taxonomy, which itself is the scaffolding around which almost all biodiversity data is organized. As indicated by its acronym, TDWG’s origins are centered on taxonomic databases, and this MoU represents an important step towards harmonizing biodiversity data in a way that will enrich and empower it to serve critical societal needs.”</em> (<strong>Richard Pyle, Former Commissioner, ICZN</strong>)</p>

<p><em>“Biological data-sharing standards are the foundation that permit meaningful exploration of the world around us and interoperability across diverse systems. This collaboration between the ICZN and TDWG represents and renews our shared commitment to open access to data and our support for science and discovery of the natural world.”</em> (<strong>David Bloom, Chair, TDWG</strong>)</p>]]></content><author><name></name></author><category term="ICZN" /><category term="Partnerships" /><category term="MOU" /><category term="Taxonomy" /><summary type="html"><![CDATA[TDWG and the International Commission on Zoological Nomenclature sign an MOU]]></summary></entry><entry><title type="html">Audiovisual Core public review</title><link href="https://baskaufs.github.io/website/news/2025/audiovisual-core-public-review/" rel="alternate" type="text/html" title="Audiovisual Core public review" /><published>2025-05-16T00:00:00+00:00</published><updated>2025-05-16T00:00:00+00:00</updated><id>https://baskaufs.github.io/website/news/2025/audiovisual-core-public-review</id><content type="html" xml:base="https://baskaufs.github.io/website/news/2025/audiovisual-core-public-review/"><![CDATA[<p>The <a href="/community/ac/">Audiovisual Core Maintenance Group</a> would like to announce the start of the public review of proposed additions to the standard.

<p>The <a href="/community/tnc/">Taxon Concept Schema (TCS) Maintenance Group</a> would like to announce the start of a minimum 30-day period for public review of a major new version of TCS, <a href="https://github.com/tdwg/tcs2/blob/master/docs/tcs-terms">Taxon Concept Standard (TCS) 2</a>.</p>

<p>TCS 2 is a major revision of TCS and comes with a proposal to change the name of the standard from ‘Taxon Concept Schema’ to ‘Taxon Concept Standard’. The purpose of the present revision was to convert TCS to a vocabulary standard, like Darwin Core, that does not prescribe a data format and that can be maintained under the <a href="/standards/vms/">Vocabulary Maintenance Standard (VMS)</a>. At this stage, we do not add any new concepts that were not already in TCS 1, but they can be proposed for addition later in a similar process that is already in place for other current TDWG standards.</p>

<p>Because this is a major change, the VMS requires a <a href="https://github.com/tdwg/tcs2/tree/master/docs/feature-report">Feature Report</a> and an <a href="https://github.com/tdwg/tcs2/tree/master/docs/implementation-experience-report">Implementation Experience Report</a>. These documents, together with the <a href="https://github.com/tdwg/tcs2/tree/master/docs/tcs-terms">Term List</a> and some other documentation, can be accessed from the <a href="https://github.com/tdwg/tcs2/tree/master/docs/tcs-terms">Documentation page of the TCS2 GitHub repository</a>. As an indication that there is still ample room for community input and improvement, no website has been created yet.</p>

<p>The best way to participate in the public review is to comment on the GitHub issues that have been created for each term. These GitHub issues are linked to from the <a href="https://github.com/tdwg/tcs2/tree/master/docs/tcs-terms">Term List</a> and can also be accessed from the <a href="https://github.com/tdwg/tcs2/issues?q=is%3Aissue%20state%3Aopen%20milestone%3A%22TCS%202%20initial%20release%22">TCS 2 Initial Release Milestone</a>. For discussions that span multiple terms, or that might result in a lot of comments, we will create separate GitHub Discussions.</p>

<p>We are organising two information and discussion sessions during the TDWG Working Sessions that will be held from 14 to 25 April, one on <a href="https://www.timeanddate.com/worldclock/fixedtime.html?msg=Taxon%20Concept%20Standard&amp;iso=20250416T1000">Wednesday, April 16, at 10:00 UTC</a> and another on <a href="https://www.timeanddate.com/worldclock/fixedtime.html?msg=Taxon%20Concept%20Standard&amp;iso=20250417T2100">Thursday, April 17, at 21:00 UTC</a>. Please go to the <a href="/community/working-sessions/2025/">Working Sessions 2025</a> page on the TDWG website to register if you are interested in attending one (or both) of these events. These sessions will be very good opportunities to learn more about and contribute to TCS. We hope to see many of you there.</p>

<p>Your comments are welcome and are important to make TCS the active standard that we want it to be.</p>

<p>Thank you,</p>

<p>Interest and task groups are the driving force for developing and maintaining TDWG standards.  The TDWG community is dynamic – people come and go – so every year we hold virtual working sessions to:</p>

<ul>
  <li>inform the wider biodiversity informatics community about the group’s work;</li>
  <li>review progress to date;</li>
  <li>engage new contributors; and</li>
  <li>set the agenda for this year’s work.</li>
</ul>

<p>The TDWG community spans the globe, so it’s difficult to reach everyone at a reasonable hour.  Some groups will hold their session twice to reach the East or West hemispheres at convenient times. But note, if the scheduled time is inconvenient or you have a conflict, we will also record every session and post the videos on the TDWG YouTube channel.</p>

<h2 id="schedule-and-registration">Schedule and registration</h2>

<p>Working session will be held over two weeks, April 14-25.  The images below show the sessions in each week.</p>

<p>TDWG is an international organization that promotes the digitization, integration, and sharing of information about the world’s biodiversity. TDWG provides a forum where individuals, projects, and institutions who manage biodiversity data can come together to share expertise and promote interoperability by promulgating standards and best practices. TDWG also publishes the Biodiversity Information Science and Standards (BISS) journal where papers on issues related to information technology and biodiversity science can be published. You would be a member of the TDWG Executive Committee, which oversees the work of TDWG: coordinates TDWG Interest and Task Groups, manages the review and ratification of standards, manages the organization’s journal, and organizes the annual meeting. These responsibilities are set forth in the Constitution and detailed further in supplementary documents.</p>

<p>Positions on the Executive are staggered two-year terms, such that no more than half of the committee will be new in any year. Towards the end of every calendar year, TDWG holds elections for terms that are expiring and need to be filled for the coming year. Officers elected this year will serve terms from 2023 through 2024. The open positions and their responsibilities are detailed below, followed by the schedule and procedures for nominations and the election.</p>

<h2 id="general-responsibilities">General responsibilities</h2>

<p>All officers, including Subcommittee Chairs, have voting rights on the Executive Committee, and are expected to participate in the committee’s conference calls, which are generally every two weeks. Executive Committee members are expected to find their own support to travel to attend the annual conference. Discounted registration to the conference may be offered.</p>

<h2 id="offices-open-for-election">Offices open for election</h2>

<h3 id="deputy-chair">Deputy Chair</h3>

<p>The Chair of TDWG holds the post for four years, two as the Deputy Chair and two as the Chair. They preside at meetings of TDWG and at meetings of the Executive Committee. They are responsible for leading TDWG, they seek advice from the Executive Committee and conveners of Interest, Maintenance and Task Groups. They write an annual update to members on TDWG’s status, activities, priorities and vision for the year ahead.</p>

<p>Unless delegated to other Executive Committee members, the Chair represents TDWG at meetings, conferences and other meetings. The Chair also opens and closes presentations at the annual conference.</p>

<h3 id="secretary">Secretary</h3>

<p>The Secretary is responsible for coordinating the activities of the Executive Committee and for the daily business of Biodiversity Information Standards (TDWG). They organize meeting agendas and take minutes. They help to coordinate the review of standards and the organization of Interest and Task Groups. The Secretary acts as a proxy for the Chair during any significant period of unavailability, and serves as the channel of formal communication to the Executive Committee for all official business.</p>

<h3 id="treasurer">Treasurer</h3>

<p>The Treasurer of TDWG holds the post for two years, which can be extended into consecutive terms. They manage the finances of TDWG, including grants, conference expenses and memberships. They work closely with the Administrator of the TDWG Secretariat as well as the other managing officers (Chair, Deputy Chair and Secretary). They write an annual financial statement, which is usually presented during a business meeting at the TDWG conference.</p>

<p>The Treasurer also has signature authority on TDWG bank accounts. As TDWG is incorporated in the USA, and the main bank account is with an American bank, the Treasurer would normally reside in the USA and hold a Social Security Number in the USA.</p>

<h3 id="chair-of-outreach-and-communications">Chair of Outreach and Communications</h3>

<p>The Outreach and Communications subcommittee is responsible for outreach and communication of the TDWG vision and mission. The activities of the subcommittee can be found <a href="/about/committees/outreach/index.md">here</a>. Most important among these are the development and distribution of communication material on TDWG standards, conferences, and current TDWG activities.</p>

<h3 id="regional-representatives-africa-asia-europe-latin-america-and-north-america">Regional Representatives: Africa, Asia, Europe, Latin America, and North America</h3>

<p>Regional Representatives give voice to the members, institutions, and projects in their region, and collectively provide a global perspective to the Executive Committee. As members of the Executive Committee, Regional Representatives have responsibility for the oversight of TDWG and the authority to approve/decline strategic initiatives, budgets, and all aspects of operations and activities. The Executive Committee also approves or declines the formation of Interest and Task Groups, as well as the ratification of standards and best practice specifications produced by Interest and Task Groups.</p>

<h3 id="minimum-information-about-a-digital-specimen"><a href="https://www.tdwg.org/community/cd/mids/">Minimum Information about a Digital Specimen</a></h3>
<p>15:00 - 16:30 UTC <a href="https://www.timeanddate.com/worldclock/fixedtime.html?msg=Latimer+Core%3A++2024+open+working+session&amp;iso=20240220T15&amp;p1=1440&amp;ah=1&amp;am=30">Translate to your timezone</a></p>

<p>This task group aims to create a TDWG standard that clarifies the levels (depth) of digitization [of or about a specimen] and the minimum information captured and published at each level. It will help to ensure that enough data are captured, curated and published against specific requirements so they are useful for the widest range of possible purposes; as well as making it easier to consistently measure the extent of digitization achieved over time and to set priorities for remaining work.</p>

<p>Conveners:  Elspeth Haston, Cat Chapman</p>

<h3 id="mapping-between-standards">Mapping between Standards</h3>
<p>17:00 - 18:30 UTC <a href="">Translate to your timezone</a></p>

<p>[A soon to be established task group of the Technical Architecture Group.]<br />
The Standards Mapping Task Group will assess the current landscape of mappings for TDWG standards and review common ways of expressing mappings. It will recommend one or more of those ways to the TDWG Technical Architecture Group (TAG) to be adopted as the TDWG recommendation for expressing mappings. The group will support standard authors to express between-standard mappings so as to be easily found, read and understood by users.</p>
