It was adopted as standard in August 2001 by IASPEI's Commission on Seismic Observation and Interpretation at the Scientific Assembly in Hanoi, Vietnam. The format is an extenstion of IMS1.0. Bulletins which use ISF comprise of a series of data blocks. These include a bulletin title block, an event title block, an origin block, a magnitude block, a phase block, etc. An important extension of IMS1.0 is the ability to add comments with keywords refering to specific parametric data. The keywords include PRIME (to designate a prime origin of a hypocentre), CENTROID (to indicate the centroid origin), MOMTENS (moment tensor solution), FAULT_PLANE (fault plane solution), PRINAX (principal axes), PARAM (an origin parameter e.g. hypocentre depth determined by depth phases).", "keywords": "", "license":[{"@type":"CreativeWork","name":"not provided"}],"about": [{"@type":"DefinedTerm","name":"Seismology", "identifier":"http://cor.esipfed.org/ont/earthcube/ADO_0000099"}], "mainEntity":[{ "@type": "CreativeWork", "url": "http://cor.esipfed.org/ont/earthcube/ECRRO_0000208", "name": "Interchange file format" } ], "encodingFormat":["application/octet-stream"], "dct:conformsTo":[{"@type":"CreativeWork","url":"http://www.isc.ac.uk/standards/isf/download/isf.pdf"}], "additionalProperty": [{ "@type": "PropertyValue", "propertyID":"ecrro:ECRRO_0001301","name": "registration metadata", "value": { "@type": "StructuredValue", "additionalType": "ecrro:ECRRO_0000156", "contributor": { "@type": "Person", "name":"Stephen M.
