Verifying HXL tags and attributes are sorted correctly

[Carol Kraemer]

Hello HXLers!

I am new to HXL tags and have been reviewing the HXL standard documentation, HDX tools, and this forum. There may not be definitive answers for my questions but I wanted to check in with you all in the hopes of finding out one way or another. :)

Ultimately, I'm looking for a list of all tags and their possible attribute combinations that would be considered a standard to be used in a project(s) I am supporting. I'd like to incorporate that list into the solution we are working on to guide users with data sheets better when trying to join those sheets with geometry (based on COD admin boundaries and have HXL headers). 

My questions:

• Gerald's Quick Reference tool uses a CSV which I could adapt for testing. Is the tool using the information found here to create that CSV?

• I noticed something when reviewing Gerald's code snippets. He mentions a bit that involves sorting the attributes into alphabetical order (See: Split. Use CsvHuman::Tag.split @ https://github.com/csvreader/csvhuman). That made me wonder if having multiple tag attributes in alphabetical order is part of the HXL standard. If so, I have also been reviewing the HXL Tag Assist | HDX Tools page that has examples and there are some that do not follow this (See: Migrant Deaths by month). Is it a HXL tag standard that in cases where there are multiple attributes for a tag that they be in alphabetical order or follow some other type of heirarchy?
  

• Are there others, like myself, requiring these comprehensive HXL tag/attributes lists for their projects and would they be willing to share their experiences with me?

• I noticed that HXL 1.1 was announced in 2017. When is 1.2 expected?

Thank you in advance!

Hello Carol,

Thanks for referencing my humble tool / quick reference.

I'm just a random guy (nobody) and not in any way part of the
"official" team and, thus, for definite answer you should consult the
official sources (or spokespersons).

As far as I can tell v1.2 is kind of changing for the worse by no
longer supporting simple language tags and adding namespaces and
including other "breaking" changes complicating the original simple
tags and attributes.

Have a great weekend. Cheers. Prost.


PS: My humble opinion about tag / attribute order - I would follow the
xml example that the order doesn't / shouldn't matter. If you want /
need a definite order, you can sort from a to z, for example.

Hi, Carol, and glad that you're interested in HXL.

Most of the time, the order of attributes does not matter. The one exception is the JSON "list of objects" encoding, where we require that the attributes be in alphabetical order with no space, to guarantee key consistency, e.g.

[
    {
        "#adm1": "Coast region",
        "#affected+idps+m": 100,
        "#affected+f+idps": 200
    },
    {
        "#adm1": "Plains region",
        "#affected+idps+m": 200,
        "#affected+f+idps": 300
    }
]

When you're using HXL in a spreadsheet, it doesn't matter.

There is a machine-readable list of the pre-defined core HXL hashtags and attributes here:

https://data.humdata.org/dataset/hxl-core-schemas

It's important to note, however, that people can create additional hashtags and attributes. There's more information here:

http://hxlstandard.org/standard/1_1final/tagging/#hashtags.extensions

Good luck with your project, and please feel free to post any future questions.


Cheers, David

Thank you David and Gerald for your responses! Both are helpful. I'll be sure to review the documentation further.

I find myself even more curious about version 1.2. How is this changing from 1.1? If I understand Gerald's response correctly, the changes are going to be significant?

We don't have a fixed date for 1.2 — our first focus is improving 1.1 adoption, before we add anything more to the standard.

If/when there is a HXL 1.2 release, we're not planning any major changes. To date, the working group has been discussing some additional attributes to provide hints for software (data types, in-cell lists of values, cumulative vs non-cumulative values), more attributes to identify affected groups (eg +disabled, +hosts), flagging potentially-sensitive data, and best practices for indicator-based survey data. All of these would be optional extras, so if HXL 1.1 still met all your needs, there would be no need to upgrade.

Cheers, David

Hi Paola,

 

That website is from the very early days of HXL, and I had completely forgotten about it. I’ve edited the page to redirect to the current home of HXL: https://hxlstandard.org.

 

As for covid applications of HXL, all of the data pipeline to feed the COVID-19 Data Explorer is based on HXL. There are probably others implementations that I don’t know about.

 

Thanks,

cj

Thank you Chad, neat updates

(changed the subject line)

I cannot see at a quick glance which are the data sources for the covid data and where is/are the source spreadsheets

for the data in the docs and referenced in the map

(sorry have limited eyesight at the moment) I wonde if they are obvious and I am just not seeing them

or if they are not so obvious

thanks
