Weekly updates

Hello Everyone,

This week I was working upon LinkedIn tool. I have added a major fields
that I feel is great. [So far these are already pushed on github] [1]

On the PR, Manu had commented "The ideal way to do the translation that
you're doing isn't to hard code it like you have. It's to provide a JSON-LD
context for the JSON you get back from LinkedIn, and then use the JSON-LD
library's .compact() method to convert the LinkedIn data to schema.orgdata."

So, over this I had a discussion and he told me quiet simple solutions to
handle this:-var linkedInData = fetchLinkedInData();
linkedInData["@context"] = myLinkedInJsonLdContext;
var schemaOrgLinkedInData = jsonld.compact(linkedInData,
mySchemaOrgContext);

So, essentially now, my task for this week would be primarily writing
contexts on LinkedIN JSON values, Also I have to understand the .compact()
method. But on looking on the structure of JSON. It seems pretty weird for
me. I would like to share a few instance here :-

1) Date of Birth - LinkedIn docs says "May return only month and day, but
not year, or all three, depending on information provided.", And a xsd:date
is valid with yyyy-mm-dd so, how to do things for this bit. What I think is
------
for (i in result.values[0].dateOfBirth) {
  if (result.values[0].dateOfBirth.hasOwnProperty(i)) {
  count++;
  }
}

if(count == 3) {
  user["birthDate"] =
result.values[0].dateOfBirth.year+'-'+result.values[0].dateOfBirth.month+'-'+result.values[0].dateOfBirth.day;
}
count = 0;
-----

which means if the date has yyyy with mm-dd then only display that and then
in context I will have something like : {... "birthDate" : "
http://schema.org/birthDate", ...}. Also is the above statement for
user["birthdate"] is wrong?

2) Say we have "educations", which is essentially an object and whose first
field _total gives  the total number of objects under it. Along with the
the each object under values may or may not have "fieldOfStudy" depending
upon school/college. So how should this be handled in contexts?

3) Similarly it goes for few other objects.

------

So, essentially once I write a valid context soon, I would test it and push
it soon :-)
