Movie and TV Metadata Library

We have created a metadata library that helps us retrieve metadata information and artwork about media files.

Here is a high level picture of how the library works:

And here is the godoc go-metadata documentation.

Install

go get github.com/amahi/go-metadata

Details

• In our implementation of this library L, the origin server acts as a client to the library
• The main entry point to L is method/function call with a media name(string) and Hint(string) such as "tv" or "movie" whose metadata we return in a structured way
• Format of the metadata returned will be a json structure with details such as cast, director, and url of cover art images that are related to it.
• The library keeps a transparent cache as part of the implementation
• Whenever L gets a request from the client, it queries a local database (the cache) to find if the requested information is present in cache already
• If it is present, L reads the data from cache and returns it
• Otherwise S will request metadata from an online API, return the results as soon as possible and cache it
• The cache should uses a LRU caching policy

Metadata Output

Lib,err := metadata.Init(1000000,"metadata.db")
if err == nil {
        data, err := Lib.GetMetadata("Breaking Bad","tv")
        if err == nil {
                fmt.Println(data)
        }
}

The above code will return a json string in the following format:-

{
   "title":"Breaking Bad",
   "artwork":"http://thetvdb.com/banners/posters/81189-22.jpg",
   "year":"2008"
}
