Also if someone can help me figure out what happens after reading and
writing geoJSON ! is features simply transformed into strings? and then when
read new features with the attributes read are being built ?
So can I simply implement my own format and maybe send the IDs of the
features over the network if the data is present at both ends ? Thank you
