TalentSignal properties relating to employer information

Hello all, I hope that we can discuss and suggest three properties 
loosely related to employer information as solutions to the following 
from our page of issues / requirements 
<https://www.w3.org/community/talent-signal/wiki/Issues,_use_cases_and_requirements>:

*1. *There should be a means of providing contact details for a 
JobPosting. Arises from analysis of Junior software developer example 
posting 
<https://www.w3.org/community/talent-signal/wiki/Examples:_Junior_software_developer>

I know this is maybe useful only in a minority of cases where jobs are 
maybe specialized, or non-standardized, but seems very common in some 
sectors, for example Higher Education or small companies, to have a "for 
further information please contact..." line in job adverts.

-- I propose we suggest a property applicationContact to JobPosting, 
with an expected value type of schema.org/ContactPoint 
<http://schema.org/ContactPoint> defintion: "contact details for further 
information relevant to this job posting"

*2. *provide Employer Overview "Description of the employer, career 
opportunities, and work environment" From Comparison of JDX JobSchema+ 
<https://www.w3.org/community/talent-signal/wiki/Comparison_of_JDX_JobSchema%2B_with_schema.org> 
with schema.org, see also issue 1829 
<https://github.com/schemaorg/schemaorg/issues/1829> point 5.

This is different to the general description that can be provided for a 
hiring organization in that it provides information relevant to filling 
a hiring requirement, for example advertising what a great place the 
organization is to work at, or signaling that legal requirements for 
hiring are being upheld.

-- I propose we suggest a property employerOverview (text) "description 
of the employer, career opportunities and work environment for this 
position"

*3. *Provide a means of giving the industry a standard code. From 
Comparison of JDX JobSchema+ 
<https://www.w3.org/community/talent-signal/wiki/Comparison_of_JDX_JobSchema%2B_with_schema.org> 
with schema.org

Currently JobPosting has a property for industry 
<https://schema.org/industry>, (the industry associated with the job 
position) but this can only be text so codes like those in NAICS or ESCO 
would be difficult to interpret.

-- This is easily dealt with by allowing DefinedTerms to be used to 
specify industry.

*Please respond.* It's important we discuss anything that I propose that 
does not meet requirements, but it is also useful in demonstrating wider 
agreement if people who agree say so. A simple "+1" in response would be 
fine.

Thank you, Phil
