add recommendations about STAC Items/Collections extensions

[vincentsarago]

in vincentsarago/MAXAR_opendata_to_pgstac#2 I've added the item-assets extension to the collections and then I'm using it (if available) in the mosaic-builder

eoAPI/runtime/eoapi/raster/eoapi/raster/templates/mosaic-builder.html

Lines 451 to 469 in 3dd87b8

	if (collection_metadata && collection_metadata.item_assets) {
	var tbl = document.createElement("table");
	tbl.classList = ["mt6"];
	tbl.style.width = '100%';
	var row = tbl.insertRow(-1);
	var cell1 = row.insertCell(0);
	var cell2 = row.insertCell(1);
	cell1.innerHTML = "Asset";
	cell2.innerHTML = "Type"
	for (let asset_name in collection_metadata.item_assets) {
	var row = tbl.insertRow(-1);
	var cell1 = row.insertCell(0);
	var cell2 = row.insertCell(1);
	cell1.innerHTML = asset_name;
	cell2.innerHTML = collection_metadata.item_assets[asset_name].type;
	}
	collection_meta.appendChild(tbl)
