RLS — Figure 9 - RoLo Architecture

-In RoLo Element class, attributes(spec) should replace to attributes.
-In RoLo Architecture class, attributes(spec) should rename to elemSpec, and should replace
to derived attribute.
-In RoLo Position class, attributes(symbolic,numeric) should replace to derived attributes.
-In Error Element class, attributes(err) should replace to derived attributes.
-In RoLo Data class, attributes(elem) should replace to derived attributes.

-The association end name should be added as follows:
-symbolic : RoLo Symbolic Position class side of association between RoLo Position and
RoLo Symbolic Position.
-numeric : ::ISO_19107::GM_Position class side of association between RoLo Position and
::ISO_19107::GM_Position.
-err : RoLo Error class side of association between Error Element and RoLo Error.
-elem : RoLo Element class side of association between RoLo Data and RoLo Element.

-The navigability notation(arrow head) should be added as follows:
-GM_Position class side of association between RoLo Position and GM_Position.
-RoLo Symbolic Position class side of association between RoLo Position and
RoLo Symbolic Position.
-RoLo Position class side of association between Position Element and RoLo Position.
-RoLo Error class side of association between Position Element and RoLo Error.
-RoLo Error class side of association between Error Element and RoLo Error.
-RoLo Element class side of association between RoLo Data and RoLo Element.
-CS_CoordinateSystem class side of association between RoLo Element Specification
and CS_CoordinateSystem.
-SC_CRS class side of association between RoLo Element Specification and SC_CRS.
-RoLo Error Type class side of association between RoLo Element Specification and RoLo Error Type.
-RoLo Error Type class side of association between Error Element Specification
and RoLo Error Type.
-RoLo Element Specification class side of association between RoLo Architecture
and RoLo Element Specification.
-RoLo Architecture class side of association between RoLo Data and RoLo Architecture.

-Because the following association is meanings to limit relations defined in superior,
we should add an explanatory note.
Position Element Specification - Position Element
Error Element Specification - Error Element

Apply the necessary modifications to Figure 9 as specified. However, the
following relations are compositions and do not show derived attributes:
RoLo Position – ::ISO19107::GM_Position
RoLo Position – RoLo Symbolic Position
Position Element – RoLo Position
Position Element – RoLo Error
Error Element – RoLo Error
RoLo Data – RoLo Element
RoLo Element – RoLo Element Specification
Thus, for these relations, replace the associations to indicate composition with
corresponding attribute names.
