+ SOME MORE SPECIFIC ISSUES TO DISCUSS
+
+ 1) Can (or should) we derive a core set of terms that completely enable the generic description of "scientific observations"?
+ General enough to enable description of any type of scientific observation
+ (how does "scientific" constrain our definition of an observation, if at all?)
+ Should we scope observation to only pertain to some specific types of interests?
+ Is there a mechanism for specializing/refining descriptions of observation to make "the framework" useful for data integration?
+
+ Are there ways to "add" domain-specific extension to the core definition of an "observation"?
+
+
+ 2) Can we establish synonymies and other mappings among terms in the various Observation Models presented so far?
+ And aside from synonymies, also clarify subsumption (more/less general) and other (part_of, constituted_of) relationships among terms in the various models? Can we identify necessary "components" of the various models for observation (e.g., are space and time information explicitly necessary?); necessary & sufficient (is it sufficient to simply have some measured value of some property of an entity?
+
+ 3) Need unambiguous definitions of Keywords* (currently massive overloading on many of those listed below...)
+
+ Observation
+ Entities
+ concrete/theoretical; thing'ish vs process'ish
+ Attributes/characteristics/features/traits
+ Procedure/method
+ Instrument
+ Measurement
+ Units
+ Measurement standards
+ Specimen/record/collection
+ Time/duration
+ Location--point, others
+ Context/composition/complex types
+ Transformations/identity
+ Essential (necessary) features or components
+
+ 4) Is modeling the assertion of some specific ("named") entity type (e.g., rock, crow) best considered as a special form of measurement (attribute type=NAME)
+ Identifying vs non-identifying names (e.g., Corvus corax vs "Plot A")
+ presence/absence measurements-- do these need to be treated (ontologically) different from say, measuring mass of a specimen?
+ names-- are names a special characteristic associated with an entity (a "name" is classifying the entity as some thing)
+ counts (is a property of set of individuals)-- how does observation model accomodate this type of measurement?
+
+
+ 5) Do "where" and "when" information pertain globally and consistently to any type of observation of interest, or are these also types of observations that can provide context for other observations?
+
+ 6) Is there ability within the Observation model, to inter-relate observations to "construct" composite and emergent entities, processes or phenomena?
+
+ 7) How can ontology/model be deployed in terms of real useful applications? Must data be ingested into a framework implementing the model, or can the model(s) be applied to data (e.g., via annotation)
+
+ 8) Is there possibility for multiple interpretations of a given observation? Is this ever necessary or desirable?
+
+ 9) How indicate that parts of tuple are dependent/independent
+ e.g. enriching context can be optional, but high dependency requires association of two observations (
+
+ 10) How rich must be set of associations/relations among observations. How specialized can these get?
+ (wolf fighting mountain lion)
+
+ 11) Is it important to be able to differentiate individual instances vs. generic assertions in a data set ("a wolf fighting a mountain lion" vs "wolves fight mountain lions")
