A difference between MPEG-21 REL and ODRL is that ODRL seems more adapted to actual transactions in the commerce environment,whereas MPEG-21 REL has designs on broader cross-vertical applicability.ODRL's primitives map more directly onto the types of terms that are found in real-world commerce.
These RELs are widely used,so it is very important to permit interworking between different systems that use these RELs.They have the same objective and they start from the same base.
They have different entities,but these try to represent the same information.After analysing both languages,we can conclude that there are four main entities in a license:
Subject:actor who performs some operation.In MPEG-21 REL it is the principal and in ODRL,it is the party.
Right:what a subject can do to an object.In MPEG-21 REL it is represented by the right and in ODRL it is the permission (right).
Object:content acted upon by a subject.In MPEG-21 REL it is the resource and in ODRL it is the asset.
Condition:describes when a right can be performed.In MPEG-21 REL it is the condition and in ODRL it is the constraint and is included in the permission (right).
As an illustration,we can consider the previous example:Alice has got a license to play a song 3 times.
Intuitively,the subject of this example is “Alice”,the object is “song”,the right is “play” and the condition is “3 times”.

不知道对不对
阿之间的MPEG - 21 REL的差异和ODRL是ODRL似乎更适合实际的商业交易环境,而的MPEG - 21 REL的对更广泛的交叉垂直设计的适用性.ODRL的原语图上更直接的是在现实世界贸易符合条件的类型.
这些RELs被广泛使用,所以它是非常重要的,允许使用这些RELs之间的不同系统之间的互联.它们具有相同的目标,他们来自同一个基地开始.
他们有不同的实体,但这些尝试代表了相同的信息.在分析这两种语言,我们可以得出结论,有4个牌照的主要实体：
主题：演员谁执行某些操作.在MPEG - 21 REL的是本金和ODRL,它是在党.
右：什么可以做一个主题的对象.在MPEG - 21 REL的是代表的权利,并ODRL它的权限（右）.
对象：内容时采取行动的课题.在MPEG - 21 REL的是资源和ODRL是资产.
条件：描述当一个可以执行的权利.在MPEG - 21 REL的条件,它是在ODRL是约束,并在权限（右含税）.
作为一个例证,我们可以考虑前面的例子：甲已经得到了许可证才能播放一首歌曲3倍.
直观地说,这个例子的主题是“爱丽丝”,对象是“歌曲”,右边是“玩”的条件是“3倍”.
