I'm creating rails application where it allow users to add geo-location data for restaurants, shops, etc., to a (Google) map and query it.
First I started with http://geoapi.com, as there is a feature for creating our own entities and querying them. But the service doesn't support my country well. So, I decided to create and store the geo-location data on my own database.
Can someone please tell me what are the best gems/plugins available for this?
I found these, but I'd like to get some feedback from you. Thanks

I would reccomend PostGIS and then use a Ruby Connector.

Using spreadsheets is definitively non-authoritative: source mappings change as you design and test your ETL jobs. A spreadsheet that once functioned as the single or authoritative catalog of all source mappings might not get updated -- or (just as likely) might get updated with incorrect or incomplete information -- as the ETL design process evolves. How do you solve your data mapping problems?
Only allow 1 person to change the dictionary; but allow everyone to view it. On one of the sheets keep a track of all change requests (yes manually): name of person, datetime, fields they wanted updated.
Sounds more like you have a version control issue than an ETL issue.

The best way is JSON. For movies you can use http://www.omdbapi.com/. Is an unofficial api for IMDB.
The JSON response from the api can be consumed using NSURLConnection you can check apple's documentation or you can simply use RestKit.

I've already released several app-books for children and the number of books is quite big.
What I want to do is create a book-stand (like news stand in iOS) and get the book together.
I think there is no way to get my apps in one app(the book-stand...) so I'm trying to remake all my previous work(the app-books) and create new app(book stand).
However, each app-book has its own interactive objects so I have no idea how to do this.
Is there any good document or any tips for this?
Can your books be made via iBooks Author? How are they interactive? If you have to go down the custom store route, I would look at epub and HTML5.
Check out the Baker Framework or HPub. Also check out various interactive PDF SDKs out there.

I'm looking to create a cron job that will collect data from multiple rss feeds and store the info in a database table.
Two example's of feeds I'll be parsing:
http://news.google.com/news?ned=ie&topic=n&output=rss
http://rss.news.yahoo.com/rss/asia
I was wondering if people have suggestions for the best rails gem to use to do this?
(Don't want to start with one to find out half way through that there are limitations/bugs.)
Thanks
Check out Feedzirra, an excellent feed reader for Rails.

We're currently using geokit to determine our users' countries of origin, but we're concerned about the volumens of queries we're going to generate. Since most of our visitors are one-offs, just caching the results isn't sufficient; we need something with its own look-up table. Is there a freely available database we can pull from every so often? Or is there an alternative we haven't considered?
After seeing this question we went with MaxMind GeoLite Country which has a free IP-to-country map downloadable in CSV format. Apparently it has some issues with AOL users but it's been good enough for our purposes so far.
Have you considered Geonames ?
