Talk:Sun

When we have the Infoboxes in a separate Database (see also: Wikidata Project) then we need also a Possibility to store the Semantic relations in that Database and extract them dynamically.
Therefore I think a strong cooperation with Wikidata should be a goal of SemaWiki.

The use of Percent-Values should be avoided wherever Possible. Instead we should take the whole Mass times Percentage.

Example: instead of:

[[Hydrogen:=73.46%]]

we use:

[[Hydrogen:=73.46% * 1.989 * 10^30 kg]]

or as a more advanced Example using existing Attributes as Variables:

[[Hydrogen:=73.46% * (Sun.Mass)]]

That is definitely a better way to do it, as it also fixes any ambiguation of wheter it is % of mass or % of volume. Fuelbottle 13:09, 16 November 2005 (CET)

The state of the atoms are ambigious in this example, I think it could be beneficial to use a syntax like:

[[Atom:=12|protons=26|neutrons=30|electrons=24]]

this would specify both state and number of elements so it would mean 12 atoms of ⁵⁶Fe²⁺, any other suggestions for syntax? For something like this I also think it would be good if it was possible to specify ouput, e.g you'd have a template like ^nucleonssymbol^charge<nowiki> then specify what it should replace: nucleons=protons+neutrons, charge=protons-electrons and it could look up that an atom with 26 protons has symbol=Fe.

Maybe it would be good to be able to specify something like a class, say class atom then hydrogen would be an instance of class atom and inherit its attributes but also be able define its own attributes. So an atom could have attributes: atomicnumber, electronconfiguration, nuclide, atomicradius. An instance of an atom would then have to have specific values for these attributes, for example iron could have atomicnumber=26, electronconfiguration=1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁶, nuclide={a specific isotope from the set of stable nuclides(isotopes)}, atomicradius=1.26. All these attributes should have a set of accepted values. An atom could have several instances of class electron. An electron class could then have attributes charge=-1.6*10^-19, spin=1/2, interactions={Gravity, Electromagnetic, Weak}, mass=9.31*10^-31kg. An instance of an electron bound to an atom could then have a different mass attribute then the general electron(for high atomic number where relativistic effects are important), principal quantum number, azimuthal quantum number magnetic quantum number and spin quantum number? Anyway an instance of an electron would then specify that electrons state. For example for a hydrogen atom an instance of a hydrogen electron could have quantum numbers n=1, l=0 and ml=0 this would imply it has the associated normalized wavefunctions Fi(fi)=1/sqrt(2*pi), Theta(theta)=1/sqrt(2), R(r)=2/(a₀^3/2)*e^-r/a₀, psi(r,theta,fi)=e^-r/a₀/(sqrt(pi)a₀ . This is the kind of information I'd like to be able to get, so I for example in the article about the hydrogen atom could click on electron type in the quantum numbers I'm interested in and then see all information about that particular instance of an electron. Does it make any sense? Fuelbottle 20:55, 16 November 2005 (CET)

Let me answer you're last question with no.
I think it should be possible to use all attributes everywhere. That articles about special group of things (like Astronomical Objects, Elements, Chemicals, TV-Shows, ...) should have a common syntax is clear. But I think, that this is not the scope of this project. This problem will get better solved by the Wikidata Project. MovGP0 01:27, 17 November 2005 (CET)

I agree that the data should be in wikidata, what I think would be nice to have in wikipedia though is a flexible way to search through that data when visiting articles about things, allowing for stuff like what I wrote above. Fuelbottle 12:39, 17 November 2005 (CET)

I think it might be a good idea to try to come up with some suggestions for syntax for wikidata and post to the wikidata talk page or something, it seems like there has very little discussion about semantic relations there. Fuelbottle 13:17, 17 November 2005 (CET)

I would do so - but I haven't seen the Wikidata Implementation in action, so it's hard to me to try and comment it. I've tried KendraBase, but it's not as flexible and handy then Wikidata will want to be.

I found something here http://epov.org/uwd/index.php/Main_Page, it looks like it's empty though and if you try to edit a page you get a list of words to select from to choose what it means. Fuelbottle 15:55, 17 November 2005 (CET)

The query for translations are impessive. But it seems that even simple editing is not working. The implementation is therefore far away from that I'd expected. Never mind - I will keep track on that project. MovGP0 23:26, 17 November 2005 (CET)
