JSON-LD + Hydra

[elf-pavlik]

I just proposed leveraging JSON-LD for civic.json https://github.com/BetaNYC/civic.json/issues/9

I would also like to propose here evaluating http://hydra-cg.com as next generation hypermedia API (you can find links to tons of presentations about it on the website!)

While on that we could also take a look at https://github.com/antoniogarrote/json-ld-macros for converting output of various APIs into JSON-LD

What is Linked Data? http://www.youtube.com/watch?v=4x_xzT5eF5Q What is JSON-LD? http://www.youtube.com/watch?v=vioCbTo3C-4

[elf-pavlik]

you can find example JSON-LD document here: https://gist.github.com/elf-pavlik/7dd02b818001adda0dea

as you see it includes names in multiple languages and uses Geonames URIs for places - some of benefits: one can get from that URI names of given place in most languages, its geolocation, nesting in administrative units etc.

$ curl http://sws.geonames.org/3020251/ -H 'Accept: application/rdf+xml' -L

ping @pmackay @jden BTW do you know anyone from http://www.citysdk.eu/developers/ ? AFAIK they use LinkedData heavily there...

[junosuarez]

@elf-pavlik I haven't seen CitySDK before, sorry

[elf-pavlik]

just found this article: http://mozillascience.org/code-as-a-research-object-metadata-for-software-discovery/ via https://github.com/mozillascience/code-research-object/issues/15

This is a continuation of some work I’ve been doing with the Mozilla Science Lab and their ‘code as a research object’ program. There’s multiple aspects to this project including work on code and GUI prototypes, discussions around best practices for making code reusable andsoftware citation. This post explores some ideas around linked data and machine readable descriptions of software repositories with the goal being to make software more discoverable and therefore increase reuse.

[pmackay]

@elf-pavlik +1 for using JSON-LD for civic.json. How much is this project defining the format now, if it is parsing it?

About using Geonames, any thoughts on how to choose appropriate ontologies from a list such as http://lov.okfn.org/dataset/lov/index.html? Is Geonames the best option?

Would any UI be of use in making it easier for people to define the civic.json files, if we extend to use JSON-LD?

I know some of the people from CitySDK, what did you want to find out?

[pmackay]

I've had a go at defining a data model for CfAPI, still work in progress. Would be great to hear from you guys if this is useful:

https://docs.google.com/spreadsheets/d/1oSq4L6rvgQlcZDLgdalzyBnFpU41RxPEjh2HlU_s3Io/edit#gid=0

Thinking through the current API and considering this modelling, a few observations:

• The data model should be defined in terms of representation objects, ideally separated from the underlying data. Currently Github details are exposed directly.
• Because of this, a fair number of properties are duplicated.
• Some of the URL properties would be better remodelled as filters, e.g.

http://www.codeforamerica.org/api/organizations/Code-for-Philly/projects becomes http://www.codeforamerica.org/api/projects?org=Code-for-Philly

The main goal here is to reuse existing vocabularies as much as possible.

[elf-pavlik]

looking at it! ping @ahdinosaur since relevant to https://github.com/open-app

[elf-pavlik]

@pmackay have you looked at https://github.com/antoniogarrote/json-ld-macros and https://github.com/antoniogarrote/geektalk/blob/master/src/apis.js

[ondrae]

You guys are awesome.

I'm sick with the flu, so it might be a few days before I respond coherently.

[pmackay]

@ondrae sure, hope you get better soon!

[ahdinosaur]

thanks @elf-pavlik. looks great so far @pmackay! :)

[elf-pavlik]

@ahdinosaur did you work on choosing terms used in open-app roadmap? https://github.com/open-app/core/blob/master/roadmap.md

i notice there use of schema:Person and org:Organization, did you miss something in schema:Organization?

[ahdinosaur]

@elf-pavlik, yes, schema:Organization does not have a Membership class for storing data about the membership (when they became a member, when they stopped being a member, the role they play as a member, etc). schema:Organization also doesn't have a good way to represent abstract roles or posts (schema:potentialAction is cool, but i should be able to associate potential actions with abstract roles), which are necessary for describing holon structures.

[elf-pavlik]

makes sense!

have you looked at http://blog.schema.org/2014/06/introducing-role.html

[ahdinosaur]

@elf-pavlik, yes, but i see it in a different light now thanks. :)

[pmackay]

I'm wondering about the github contributors value - would the proper way to model that be to define a person object, and use that? What is supporting http://www.codeforamerica.org/geeks/ in the API currently?

I've done a number of other schema updates...

[ondrae]

I don't have any opinions on how to model people, yet. We're working on some other ways to track individual activity soon. I'm letting that work, and yours, influence how we model people in the code.

The info about the Geek of the Week on /geeks is hard coded for now.

I'm excited to see what other improvements you've made.

[elf-pavlik]

My apologies for silence, lately I've joined W3C Social Web WG and we currently work on topic of social syntax/vocabs. I'll pick up this thread once we have some progress in WG, we hope to confirm direction on mentioned topic by Sep 23rd.

[elf-pavlik]

I would like to move on with expressing relations Person, Organization and Projects (3 way n-n) especially for https://github.com/codeforamerica/cfapi#projects-list

@pmackay would you like to have a video call sometimes next week?

[pmackay]

@elf-pavlik we could, maybe Thurs/Fri?

[elf-pavlik]

@pmackay sounds good! let's move it to PM :email: i start playing with JSON-LD Macros, you can find very basic CFAPI example here https://gist.github.com/elf-pavlik/86238a1a80ec34795b33 as well as more json-ld macros examples for popular services

[ahdinosaur]

@elf-pavlik @pmackay, can i listen in on this? i'm collaborating with some folks on the same domains.

[ondrae]

Just found that http://g0v.tw/ is using their own version of civic.json on most of their projects called g0v.json. It uses json-ld too. They then display the projects on http://hack.g0v.tw/project

@clkao did you come up with g0v.json or get the idea from BetaNYC?

[clkao]

@ondrae I think we got that separately then found BetaNYC's effort. a few of us meant to discuss civic.json during CfA summit but didn't manage to at the end.

[elf-pavlik]

@bcomnes I see you requested IE membership in W3C Social Web WG https://www.w3.org/wiki/Socialwg#Applied_for_Membership

I would like to propose CfA as one of Social Web use cases, would you like to join the call we plan with @pmackay and @ahdinosaur? (most likely Friday evening UTC).

[bcomnes]

@elf-pavlik I have volunteered and worked with the organizers for the Code for Portland group in PDX, which is also a CFA brigade. There is a meeting this evening that I may attend and will bring this to the organizers attention and see who can best join that call (maybe me).

[elf-pavlik]

I just noticed @taisukef suggesting relevant session for upcoming W3C TPAC

Current develepmont of what was formerly known as https://github.com/open-app/core/blob/master/roadmap.md (404) know happens in similar spaces such as World Wide Holonic Economic Ecosystem, for who would want to follow the trail.
