hey @SamFritz all our DataFrame fields have been renamed to lowercase:
https://github.com/archivesunleashed/aut-docs/blob/master/current/dataframe-schemas.md

but in lots of cases, field names are still upper case, e.g., here:
https://github.com/archivesunleashed/aut-docs/blob/master/current/collection-analysis.md#extract-top-level-domains

import io.archivesunleashed._
import io.archivesunleashed.udfs._

RecordLoader.loadArchives("/path/to/warcs", sc).webpages()
  .select(extractDomain($"Url").as("Domain"))
  .groupBy("Domain").count().orderBy(desc("count"))
  .show(20, false)

hey @ruebot can you confirm that Url should be changed to url and Domain changed to domain?

@lintool if you're going to join in on reviewing, you'll want to review these docs: https://github.com/archivesunleashed/aut-docs/tree/docusaurus/docs

I'll check though for column name issues now.

• “Secondly, if there is time, we can begin to think about how” —> Secondly, we can begin to think about how”

Collection Analysis

• Question: are we leaving in” TODO: Add script for the case where I only want to know the location of one resource.”?

@SamFritz I think I got most of it. Just pushed things up locally, and have a preview here https://ruebot.github.io/aut-docs-redux/

Suggestion: We should be descriptive on the “here”(s) for accessibility purposes?

I don't follow. Can you link to an example?

Questions: Can we add “which java” to find out where it lives, just like python instructions?

Maybe? @ianmilligan1, thoughts?

Question: are we leaving in” TODO: Add script for the case where I only want to know the location of one resource.”?

Yep, for now.

Re: which java - my head kind of hurts when it comes to Java, as I have so many different java's on my machine that I point to in my .bash_profile. So I probably wouldn't add which java here.

A few catches:

usage.md:

• "There are a two options" -> "There are two options"
• "PySpark with the Java/Scala package, and the Python bindings" -> "PySpark with the Java/Scala package, as well as the Python bindings"

aut-at-scale.md:

• "Apache Spark has a great Configuration and Tuning guides that are worth checking out" -> "Apache Spark has great configuration and tuning guides that are worth checking out."

The rest are one-offs:

• text analysis - inconsistency in the RemoveHttpHeader in the doc wrapper vs the RemoveHTTPHeader in the script itself.
• link analysis - in the intro text, maybe change "Though, we do provide one example below that provides raw data" -> "That said, we do provide one example below that provides raw data"

I also did get a page not found when clicking forward to https://ruebot.github.io/aut-docs-redux/docs/rdd-filters. Somewhere there's a pointer to rdd-filters rather than filter-rdds

Otherwise things are looking good to me!

Python line continuations with backslash should have a space, per PEP8:

from aut import *

WebArchive(sc, sqlContext, "/path/to/warcs")\
  .webpages() \
  .select("url") \
  .show(20, False)

So, slash on first line needs extra space; others are fine. Issue throughout docs.

Thanks @lintool - I fixed those brackets in 1b96f0f above.

Only remaining TODO is #72.

BTW I have an ongoing draft PR for typo fixes/clean ups etc. at #76.
