Hi Ed,
I've noticed that you have 2 properties, Physiognomy and Satellite sensor status cotyped as LC and Topic. I'm guessing this might have been an errant mistyping due to autocomplete. I'd like to detype them - is that ok?

Sure but they were purposeful typings. LC is a bucket type I created for all types that have something to do with land cover mapping even if they are best placed in another domain. They are usually topics too. No problem if you want to detype them. I've put that project on the shelf for a little bit and know how to pick it back up later.

Thanks, Ed.
I think Physiognomy and Satellite sensor status (the properties) should be separate, discrete objects than Physiognomy and Satellite sensor status (the topic and LC) and not conflated. You do have a separate Physiognomy type (http://www.freebase.com/tools/schema/user/spatialed/land_cover/physiognomy) - should that have included types of topic and LC?

the type /user/spatialed/default_domain/land_cover has as an included type /user/spatialed/default_domain/classification_system.
but /user/spatialed/default_domain/classification_system has /user/spatialed/default_domain/land_cover as an included type too,
creating a cyclic included types relationship. is this an error?
-
Where do you see land cover as an included type of classification system? I don't see land cover (or any other types) as an included type of classification system. However, classification system is an included type of land cover. The name is actually "Land cover classification system" to identify it as a subset of "Classification system". I've changed the type key to reflect this nestedness. The new address is /user/spatialed/default_domain/land_cover_classification_system
If there is a cyclic relationship somewhere let me know and I will change it because it would be an error.

i'm seeing a cyclical relationship in:
http://freebase.com/view/schema/user/spatialed/default_domain/satellite_image_product
a satellite image product has itself as an included type.
is this an error?
-
you have a cyclical relationship:
http://freebase.com/view/schema/user/spatialed/default_domain/satellite_image_product
i click on the first included type "Land cover classification system" of "Satellite Image Product"
http://freebase.com/view/schema/user/spatialed/default_domain/land_cover_classification_system
and "Land cover classification system" has as its first included type "Satellite Image Product"
-
Good catch. Thanks. I was still figuring out how to work with Included types when I created those schema. They probably still need some work but I removed the cyclical relationships. Let me know if you see any other problems. I plan to get back to these schema and start adding a lot more data for them May-June.

Hi Ed,
I know you subscribe to the data-model list, but I wanted to let you know that I noticed that your type /motorcycle/motorcycle_product_review has a property that expects one of the types listed in the email. You can review the email here.

Ed, there were a couple of odd topics that were typed by you as units of moment of force (kilograms per cubic meter and pounds per square inch). I have de-typed them, but you may want to check if you had any properties using them as units. Please double-check them.
-
Ok. Why are they odd? I added them because torque is commonly measured in terms of pounds per square inch or kilograms per cubic meter. How should I enter torque data?
-
Torque is usually measured in force × distance: foot-pounds, Newton-meters (the SI unit). This can be decomposed to mass × area ÷ time-squared; I have never heard of torque measured in units of density (mass ÷ volume, kg/m³) or pressure (force ÷ area, psi). Where are you seeing torque measured in these units? It may be a field-specific jargonistic
use of the term, but it’s not one I’ve heard before. -
Oops. I meant to add inch-pounds and went with an existing topic I mistakenly thought was synonomous. Similarly, I mistakenly thought that kilograms per cubic meter was a metric equivalent. Inch-pounds does need to be included though.
-
You should be able to add inch-pounds. Add a new instance of Unit of Moment of Force and give it a name. You must also give it a “Dimension” (Torque) and a “Canonical Abbreviation” (in-lb?) in order to be able to use it with a property definition. An equivalence in Newton-meters is also encouraged (0.112984829, I believe).
