Classification of type of observation Cardinality: 1..1 CodeableConcept	A code that classifies the general type of observation being made.	value is bound to Observation Category Codes (9 codes) codinghas cardinality: 1..1
Type of observation (code / type) Cardinality: 1..1 CodeableConcept	Describes what was observed. Sometimes this is called the observation "name".	value is bound to LOINC Codes (>1000 codes) codinghas cardinality: 1..1
Clinically relevant time/time-period for observation Cardinality: 0..1 dateTime	The time or time-period the observed value is asserted as being true. For biological subjects - e.g. human patients - this is usually called the "physiologically relevant time". This is usually either the time of the procedure or of specimen collection, but very often the source of the date/time is not known, only the date/time itself.
Actual result Cardinality: 0..1 Quantity	The information determined as a result of making the observation, if the information has a simple value.	system is fixed to http://purl.obolibrary.org/obo/uo.owl systemhas cardinality: 1..1
High, low, normal, etc. Cardinality: 0..* CodeableConcept	A categorical assessment of an observation value. For example, high, low, normal.	value is bound to Observation Interpretation Codes (57 codes)
Protocol
How it was done Cardinality: 0..1 CodeableConcept	Indicates the mechanism used to perform the observation.	value is bound to Observation Methods (>1000 codes)
Context
Who and/or what the observation is about Cardinality: 1..1 Reference	The patient, or group of patients, location, or device this observation is about and into whose record the observation is placed. If the actual focus of the observation is different from the subject (or a sample of, part, or region of the subject), the focus element or the code itself specifies the actual focus of the observation.	value must point to a RareLink IPS Patient
