However, might want to go one step further and auto-generate this list from our own properties. For instance, all of our domains are marked with the [Property:Is domain] and our facilities are marked with the [Property:Is facility]. If you view the pages for [MediaWiki:Smw_allows_list_Domains] and [MediaWiki:Smw_allows_list_Facilities], you will see that they have the correct unordered lists. But if you view the source, you will see something like the following (from [MediaWiki:Smw_allows_list_Domains]:

This autogenerates the correct ordered list for everything marked [Property:Is domain]. One might think that using the |format=ul would create the appropriate unordered list format (with the * in front), but it apparently does not. Therefore, this query removes the page link (link=none) and reduces the entry to simple text, and then it uses the template ([Template:Starlist_for_allow_value_list]) to render the text with a * in front of it (''See [https://www.mediawiki.org/wiki/Help:Templates help on templates) for an explanation of templates'''. This works well.

If, for some reason, you do enter a value that is not on the allowed list of values, the page will render a small warning icon.

===Philosophy on New Properties===

Basically, there isn't much of one. The beauty of properties is that you can add them, and mix and match them to form unique queries. I suspect that there will be a query that shows every piece of equipment in the Maker Hub. There could be one that shows everything - equipment, tools, supplies, etc. There could be one that shows equipment in the machine shop. And then, one can create more focused properties. I have initially created two as examples - [Property:Is sheet metal equipment|Is sheet metal equipment] and [Property:Is soldering iron equipment|Is soldering iron equipment]. I suspect that we will mark the [[Sheet Metal Shear]] as both [Property:Is equipment|Is equipment]  and [Property:Is sheet metal equipment|Is sheet metal equipment]. This way, the [[Sheet Metal Shear]] will show up on lists that show equipment as well as lists that show the more focused sheet metal equipment. However, [[Soldering Irons]] will be marked as [Property:Is equipment|Is equipment], but the [[Weller_WES51]] will only be marked as [Property:Is soldering iron equipment|Is soldering iron equipment]. This means that [[Soldering Irons]] will show up on a general equipment query, but the [[Weller_WES51]] will not. This decision is somewhat arbitrary and is left to the Wiki editors. In this case, there is no reason to see every particular type of soldering iron on a general equipment list, but the sheet metal sheer will show up, like this: [[File:small_warning_icon.png|12px|Small Warning Icon]].
