DwC-DP Integration at GBIF
GBIF is close to supporting Darwin Core Data Packages end to end, with typed and stricter validation, while keeping Darwin Core Archives fully supported.
Federico Mendez, Mikhail Podolskiy ↗
A community-curated controlled vocabulary for fossil collections using dwc:materialEntityType
A granular, community-derived vocabulary for dwc:materialEntityType would let users filter fossil records by what the material actually is, which basisOfRecord cannot do.

A new standard for restricted access (sensitive) species data
A proposed Darwin Core extension would record why data were restricted and what treatment was applied, in a one-to-many way similar to MeasurementOrFact.

Machine-Ready Botanical Data: Mapping Integrated Collections and Traits with Darwin Core Data Package
Darwin Core Data Package can serve as a semantic integration layer for a botanical garden's diverse collections and trait data, and MBG's draft mapping is offered for community refinement.

Open Digital Curation and Round-Tripping Biodiversity Data Enhancements Across Collection Infrastructures: Six Years and 50 Million Links in Bionomia
Round-tripping is much harder than expected, and data managers must fully populate identifiedBy so taxonomists' expertise is credited.

A framework for aligning collections data with the global data ecosystem from data creation to extension in the Smithsonian National Museum of Natural History Department of Paleobiology
Making paleo collections work in the global data ecosystem needs an iterative, full life-cycle framework, not one-off digitisation.

Aligning An Evolving Global Data Model To Software With Global Ambitions: GBIF x TaxonWorks
TaxonWorks and DwC-DP have converged conceptually, but exchange between rich models will always be lossy, so mappings should be recorded explicitly.

From Specimens to Networks: Darwin Core Data Packages in Practice
The Darwin Core conceptual model and Data Package give material entities a rich, relational context that flat Darwin Core Archives could not express.

Managing high-volume specimen movements in the entomological collection of Naturalis with a new type of record
A 'lot' record linking taxa to storage units makes high-volume physical moves cheap to record and tells staff where each taxon is.
Myriam van Walsum ↗
Mapping the Relational Data Schema of the Diversity Workbench (DWB) to the Darwin Core Data Package Data Model to fit better to GBIF´s New Data Model
DwC-DP promises to carry the relational richness that previously pushed GFBio centres to ABCD, and a first DWB-to-DwC-DP prototype via the test IPT works.

Material Samples and Occurrences in Darwin Core Data Packages: Practical Experiences from DINA
DINA's material-sample model maps well to DwC-DP, so DINA wants to publish without synthetic occurrences and needs community conventions for consumers to derive them.

SYM42 discussion: DwC-DP profiles, deriving occurrences, ABCD's future and system boundaries
Richer relational models bring the community together but raise hard governance questions about profiles, occurrence derivation, system scope and link persistence.

Enabling machine-readable access to biodiversity data through federated semantic querying
Distribute the data, not the infrastructure: cloud Parquet plus OBDA query rewriting gives a virtual Darwin Core knowledge graph without duplicating data into RDF.

TDWG 2026 Unconference: pitches, topic voting and breakout report-backs
The Unconference showed the community's priorities (controlled vocabularies, AI readiness, project sustainability, Wikidata, Darwin Core data packages) and started several follow-up groups.
