Action items updates:

Rules for defining term_exists - led by Stephane Meystre - COMPLETED
Mapping of CUIs to standard terminology - led by Juan Banda - COMPLETED, here's the link to the repo: https://github.com/thepanacealab/OHDSIananke
Mapping of Note Types to LOINC/standard vocabulary - Karthik Natarajan, Ruth Reeves, Jon Duke and Hua Xu will work together on this: Multiple note types sent to Jon. To be followed up.
Landscape Analysis of section identifier systems and proposal of a standard terminology for use - led by Hua Xu with help from Karthik Natarajan: SecTagger and section header ontology obtained from Vanderbilt. Need to figure out normalization.
Examples and rules for term_temporal - led by George Hripsack (Sunny): The CDM to be updated with the definition below:
- If in the past, then term_temporal is PAST. And term exists has to also be positive. You never have term_exists=no with PAST.
- If not in the past, then term_temporal is blank.
- If it is from the same inpatient admission, that is not considered past, but still in the present.
- More discussion needed on whether to merge term_exists and term_temporal into one variable, or to leave them apart.
Standardization of term_modifiers and values - led by Hua Xu: To define modifier list and normalized values for each modifier were the tasks. Initial review were from SHARPn modifiers (also used in cTAKES) and Wendy Chapman's group (https://github.com/Blulab-Utah/resource_ontologies)
