A future scenario…

- Research agenda?

- Connection to scientific research themes and initiatives?

- Chances for young researchers?

Organization of dendrochronologyThe role of digitization

Organization of dendrochronologyVerifyable data and results?

Solution: the DCCD

The DCCD projectMission, vision, strategy

Phase 1: inventary of needs, developing concepts and network (workshops, questionaires, interviews)Start-up subsidy NWO/GW IM 2006-2007

Phase 2: development of infrastructure and content Low CountriesSubsidy NWO/GW IM 2007-2012

Phase 3: internationalization, research and publication; EU-fundingSubsidy NWO/GW IG 2010-2013

17

Mission: emancipation of historical dendrochronology

Vision

- Connection - Transparancy- Sustainability - Visibility


18

Strategy

- Realising standardization and exchange of data and metadata

- Realising stustainable repository focussed on cultural and natural heritage

- Realising intersectoral collaboration (within the discipline and with other fields, nationally and internationally)

While doing this: be aware of the whishes and needs of the private sector

The DCCD is growing

- France: dendrochronologists have become involved

- Finland: dendrochronologists are switching to TRiDaS

- Sweden: national application for creating Swedish DCCD (to be connected to DCCD)

- Commercial software: incorporating TRiDaS

- Software USA: first open source TRiDaS-based measuring and analytic system has been lauched (TELLERVO)

Roman periodDe Meern 4: AD 100

Roman periodClustered data 100 BC-450 AD

33

Levees Rhine-Meuse delta:no wood was moved

East Brabant sandy soils: some wood was moved


Roman periodLocally grown oak

34

Import Rhineland (harbour, temple)lots of wood was moved


Roman periodOak from German Rhineland

35

Flemish timber: used in ‘Dutch’ ships excavated in Central NetherlandsConclusion: Roman coastal infrastructure (water)


Roman periodNew: a Flemish connection

36

16th century ADNew: tax evasion?

AD 1497: taxes when passing the Sont

In additionResearch funding NWO Humanities 2012-2017: The Dark Age of the Lowlands

in an interdisciplinary light: people, landscape and climate in the Netherlands

between AD 300 and 1000 (3 PhD students, UU)


The DCCD infrasctucture has led to

• International data standardization

• Access to and sustainable management of these data

• New research questions and results

• Research funding
