The Alpharabian tuning is an 11-limit version of just intonation- specifically the version that is limited to the 2.3.11 subgroup. Although the core of Alpharabian tuning consists of those intervals with ratios involving integers whose only prime factors are 2 and 11, Alpharabian tuning can also contain small powers of three in their ratios, with the largest of these being 3^6. That said, within Alpharabian tuning, there's a distinction between "Alpharabian" and "Betarabian" intervals, with "Alpharabian" intervals generally being simpler and or nearer to either 3-limit intervals or the 2.11 core subgroup than the nearby "Betarabian" intervals, which often differ from their Alpharabian counterparts by a rastma.
