The best example I can think of is a number of Diamondback's, Dauntless's, and Quad's worlds. They usually feature large creative creations that players are simply meant to observe and take inspiration from.
I believe all three of us use the "construction" attribute, simply to denote that we are currently hosting this map while we are building something/an expo of builds that are complete, regardless of whether the map is finished or not. Everything is laid out where there isn't much hunting for secrets. More of a showcase.
I only use "exploration" attribute on my dig deep world, more on the basis that each build has something unique to explore inside of it. (i.e. Hogwarts has eight sets inside of the castle, and several more underground areas that require a player to be actively searching for a new path). Hence the idea that the player is exploring each build to discover new stuff.
