Smart Data Models’ Candidates repository<\/a> now includes two more ETSI SAREF<\/strong> extensions, both built around smart metering: saref4watr<\/code><\/strong> and saref4grid<\/code><\/strong>, together contributing
\n89 candidate models<\/strong> \u2014 the largest pair in this translation round. Both ship the full Candidates artifact set \u2014 a JSON Schema, an NGSI-LD @context<\/code>, and all four example serializations \u2014 validated against its own schema.<\/p>\n

SAREF4WATR \u2014 49 models<\/h2>\n

SAREF4WATR<\/a> (ETSI TS 103 410-10) spans the entire water domain: natural water bodies (rivers, lakes, aquifers, glaciers), the infrastructure that moves and treats water (distribution systems, treatment plants, gauging stations, hydroelectric plants), individual field assets (pipes, valves, pumps, fire hydrants, manholes), and smart water meters with their tariff models.<\/p>\n\n\n\n\n\n\n\n\n\n

SAREF4GRID \u2014 40 models<\/h2>\n

SAREF4GRID<\/a> (ETSI TS 103 410-12) is SAREF’s extension for smart electricity metering<\/strong>, explicitly designed to mirror DLMS\/COSEM (IEC 62056)<\/strong> so its classes map cleanly onto real meter data \u2014 every COSEM object carries an OBIS code (hasObis<\/code>), the same identifier engineers use on the wire. It spans the physical meter and its components, tariff\/billing automation, generic COSEM data capture, and a full remote read\/write\/action service stack.<\/p>\n\n\n\n\n\n\n\n\n\n
