# Alexa Metal Archives Lookup

This is the backend for the Alexa skill “Metal Archives Lookup” which

provides an interface to look up band information at the excellent

Metal Archives database.

At this point, it is only possible to request a simple band lookup. To

look up information about the band _Forgotten Tomb_, say “Alexa, tell

Metal Archives to look up the band Forgotten Tomb.”

There are three types of answers:

  - If only one band with that name is found (e.g. there is only one

    _Root_), the answer will consist of a short information

    about the band’s genre, country of origin, date of formation and

    whether or not they are still active.

  - If there are between two and four (inclusive) search results

    (e.g. there are two bands called _Forgotten Tomb_, the answer will

    briefly summarize the bands’ countries of origin and genres.

  - If there are more than three search results (e.g. there are loads

    of bands called _Mayhem_, the answer will only state the number of

    bands of that name.

There are lots of ways, this skill could be extended: It could prompt

to ask for a specification of what band to select when there is more

than one band, it could provide interfaces for looking up albums,

songs, artists etc. It could even be extended to support more

sophisticated queries like “Who designed the cover art for

Dissection’s second album?”
