The document discusses the development of a cross-domain vocabulary for observation data in science, addressing challenges in data integration and analysis. It emphasizes the importance of standardized protocols, procedures, and terminologies for enhancing environmental monitoring and data cataloguing. Various types of samples and observations are defined, along with references to existing standards and frameworks like W3C vocabularies.

- 17. Sample = result of Act-of-sampling A ‘sample’ is a thing or subset which is intended to be representative of a larger thing or set … … created or selected for the purpose of making observations to determine the value of one or more properties, traits or qualities of the larger thing C3DIS 2018-05-29 | Cox | Standards for science data17 The essential property of a sample is the 'is-sample- of' relationship with the larger thing. https://goo.gl/KBvkgW
- 18. Types of sample A material sample or specimen is typically selected to allow ex-situ observations A statistical sample or subset is a specified number of individuals from a population A spatio-temporal sample may have the same dimension but a smaller extent than the thing which it represents, or a lower topologic dimension than the thing which it represents C3DIS 2018-05-29 | Cox | Standards for science data18
