Welcome to DCC2GO
Glossary to DCC Quick Survey
Small Collaborative Project - DCC2GO "Supporting the implementation of Digital Calibration Certificates in the European metrology community", has been implemented to help the metrology community in general but also specifically the Small and Emerging NMIs and DIs (SEND) to start the process of evolution from paper based Calibration Certificates to electronic Digital Calibration Certificates.
It is understood that there is a lack of training information suitable for the SEND community and the purpose of DCC2GO is to provide this information.
ACC | Analogue Calibration Certificate - this is a way to refer to paper based Calibration Certificates. As paper documents are clearly not digital hence the use of the logic based analogy "if its not digital it must be analogue" |
DCC | Digital Calibration Certificate - A computer file based version of a Calibration Certificate. This could be a PDF file or an XML file containing the information typically stored in a paper based certificate (as a minimum), that is capable of being digitally signed and secured. |
D-SI | Digital SI |
XML | XML Document |
XSL | eXtensible Stylesheet Language |
XSLT | An XSLT (Extensible Stylesheet Language Transformations) file is used to convert the contents of an XML data file into a different XML document. Typically XSLT files are used to take as input an XML file and to output a more readable, presentable version that is easily readable, e.g. for viewing on screen or for printing. |
XSD | XML Schema Definition is a World Wide Web Consortium (W3C) recommendation that specifies how to formally describe the elements in an Extensible Markup Language (XML) document. Basically it defines the type of information that is allowed in the XML file and so can be used to validate the contents of an XML file. |
TraCIM | Traceability for computationally-intensive metrology - An online service is provided by PTB to provide traceability to mathematically intensive computiaional based analysis |
SEAL | Within the European eIDAS framework, a Seal is a digital signature assigned to a work role or organisation rather than an individual person. For example, the work role could be “Head of Calibration Services”, rather than “Fred Smith”. This could allow DCCs to be signed by a “work function” rather than an individual person who may leave a business. |
Digital Signature | A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents |
Electronic Signature | An electronic signature, or e-signature, refers to data in electronic form, which is logically associated with other data in electronic form and which is used by the signatory to sign. This type of signature has the same legal standing as a handwritten signature as long as it adheres to the requirements of the specific regulation under which it was created (e.g., eIDAS in the European Union, NIST-DSS in the USA or ZertES in Switzerland). |
Meta-Data | Data that describes Data. Typically meta-data depends on the users point of view. One persons meta-data is another persons data. Therefore the context of the viewpoint is important. |
IoT | Internet of Things - describes the network of physical objects—a.k.a. "things"—that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the Internet. |
Smart-Sensor | A sensor capable of working as an IoT device |
GUM | Guide to the Expression of Uncertainty in Measurement |
CODATA | Worldwide organisation responsible for managing the values associated with fundamental physical constants e.g. Planks Constant |
VIM | International Vocabulary of Metrology |
ISO/IEC 17025 | An international standard that enables laboratories to demonstrate that they operate competently and generate valid results, thereby promoting confidence in their work both nationally and around the world |
RDM | Research Data Management |
FAIR+X | Finable, Accessible, Interoperable, Reusable + Traceable |
Uncertainty | The expression of the statistical dispersion of the values attributed to a measured quantity |
Coverage Factor | Factor that indicates the confidence interval of a measurement. The coverage factor of k = 2 generally indicates a 95% confidence that the measured value will fall inside the uncertainty interval. |
eIDAS | eIDAS is an EU regulation on electronic identification and trust services for electronic transactions in the European Single Market. It was established in EU Regulation 910/2014 of 23 July 2014 on electronic identification and repeals 1999/93/EC from 13 December 1999 |
