For single source data, standardization of these default values may be through assigned mapping values, against a lookup table, or based on a defined pattern or algorithm within the data.
对于单个源数据，这些默认值的标准化可以通过根据一个查找表或定义好的模式或算法，在数据中指定映射值来完成。
If new standards exist, data should be mapped to those new standards through mapping values, against a lookup table, or based on a defined pattern or algorithm.
如果存在新的标准，那么应该通过映射值，根据一个查找表或一个定义好的模式或算法，将数据映射到那些新的标准上。
We can quickly define some initial rules based on the mapping table above, as Listing 4 shows:.
我们可以基于上面的映射表格快速地定义一些初始规则，如清单4中所示。
