The goal is to produce examples of digital reports and certificates to assess the scope and challenges of digital transformation in those particular measurement services. This paper focuses on the Reference Material Certificate effort of the pilot project. Our aims for this part of the pilot project are: to generate a digital Reference Material Certificate from certification data; descriptive information about the material, and other data and metadata as needed; to generate a human-readable report from the digital Reference Material Certificate; and to hold a workshop to gather stakeholder feedback. The challenges for NIST include the diverse and complex information presently contained in NIST certificates, converting values to non-SI units to match the needs of stakeholders, and format updates to NIST Reference Material Certificates necessary to allow for machine generation. Other practical challenges include the wide variety of Reference Materials offered by NIST, as well as the needs of internal and external stakeholders. This presentation will report on the progress of the NIST effort and discuss some of the challenges and solutions to producing Digital Reference Material Certificates.</p>","PeriodicalId":72053,"journal":{"name":"Acta IMEKO (2012)","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10161391/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9800430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
