---+!! Observations Task Group Wiki

This is the wiki for the the TDWG Observations Task Group (OTG), which is a subgroup of the [[http://www.tdwg.org/activities/osr/][Observations and Specimen Records Interest Group]].  The [[http://wiki.tdwg.org/twiki/bin/viewfile/Observational/WebHome?filename=TDWG_OBS_Task_Group_Charter.pdf][Observations Task Group Charter]] focuses on models and specifications to realize observational data interoperability.  The goal of this task group is to create a core semantic model for observational data in the ecological and environmental sciences. Holistic, integrative, and large-scale science would benefit from better data discovery, interpretation, and integration both within and across disciplines that would be enabled from a common observational data model. This is necessary because there is an enormous quantity of observational data that is gathered by very diverse methodologies and stored in various formats. Additionally, a variety of observational data models have been developed, but none are sufficiently comprehensive.

---+++ Observational Data: a definition
A working definition is that observational data are the outcomes of acts of measurement using particular protocols within the context of any objective scientific measurement activity. Examples include data from survey or monitoring efforts, controlled experiments, and sensor-derived measurements.  In each case, the basic or atomic notion of an observation represents the outcome of some measurement taken of a defined attribute or characteristic of some “entity” (e.g., an organism “in the field”, a specimen, a sample, an experimental treatment, etc.), within some context (possibly given by other observations).  Every observation entails the measurement of one or more properties of some real-world entity or phenomenon.

| Note: this site is under development. The co-leaders of the Observational Data Subgroup are currently preparing this Wiki. We hope to have this ready by 17 July. We encourage anyone interested in this topic to register and add content. Thank you, Steve Kelling. |

This wiki is used by the Taxonomic Databases Working Group (www.tdwg.org) to collaborate on the integration of observational data into the existing biodiversity informatics infrastructure. 

*To begin:*

*Our latest version of an observation definition is as follows:*

| "An observation characterizes the evidence for the <u>presence or absence</u> (OrganismOccurrence) of an organism or set of organisms through a <u>data collection event</u> (DataCollectionEvent) at a <u>location</u> (ObservationLocation). Observations are not necessarily independent and <u>could be linked</u> (LinkingObservations) via characteristics such as time, place, protocol, and co-occurring organisms." |


*Draft of CoreConcepts to be included in Observational Data Standard.*


For more information, please contact: 
   * Steve Kelling (stk2-at-cornell-dot-edu), Subgroup Convener,
   * Lynn Kutner (lynn_kutner-at-natureserve-dot-org)
   * Denis Lepage (dlepage-at-bsc-eoc-dot-org)
   * Bruce Stein (bruce_stein-at-natureserve-dot-org)
   * Ricardo Pereira (ricardo-at-tdwg-dot-org), System Administrator, or
   * Roger Hyam (roger-at-tdwg-dot-org), also a System Administrator.
