WITSML - Realtime Record Component Schema The id of the group that this record represents. The combination of id and seq should be unique within a subscription. The one-based sequence of records for one group in this subscription. The first record for a group should have a sequence number of one and each subsequent record for that group should increment by one. The time index for the record if the interval type is time-based. Along hole measured depth of measurement from the drill datum. The data values for the record. A comma delimited list of data values with one value for each channel in the group (e.g., "xxx,yyy, zzz"). For array channels, the value of the array channel will be a space delimited list of values that are contained within the commas that delimit the value for that curve (e.g., "xxx,aa bb cc,zzz"). This essentially represents one row of a table where the channel mnemonics represent the column headings.
