Description

There are some errors in the ORC format specifications:

1. In specification/ORCv1.md and specification/ORCv2.md, the following sentence appears twice in the description of "Patched Base”:

Data values (W * L bits padded to the byte) - A sequence of W bit positive
values that are added to the base value.

2. In specification/ORCv0.md, specification/ORCv1.md, and specification/ORCv2.md, there is an error in the description of “Map Columns”:

Maps are encoded as the PRESENT stream and a length stream with number
of items in each list. —> The last word “list” should be changed to “map”

3. In specification/ORCv1.md and specification/ORCv2.md, the word “BloomFilterEntry” should be changed to “bloom filter entry”, as “BloomFilterEntry” does not exist in the source code or ProtocolBuffer definition.
