100 Bestsellers in FluidDB: So What?¶

So What?¶

Why should you or anyone else care that I’ve published this data to FluidDB? After all, the Guardian made the data available on Google docs, so anyone can do anything with it anyway. What’s the benefit of having it in FluidDB? I’m going to try to show a few things that might convince you there’s something interesting about putting this sort of data in FluidDB.

1. Query¶

The most obvious thing is that you can query data in FluidDB from anywhere with internet access without even having an account. For example, the query to find the best-selling book from the list in FluidDB is this:

miro/bestsellers-1998-2010/rank = 1

You can issue this query from anything that can talk to FluidDB and it should return the object corresponding to The Da Vinci Code, by Dan Brown. Here are a few ways of doing just that.

• You can use the FluidDB Explorer and just paste the query into the query box. It should locate the object (identifying it by its about tag, which is book:the da vinci code (dan brown) and also by its FluidDB ID, which is e7fee95f-4dcd-458b-8893-b56352d455cf. If you then click on either the about tag or the object ID, the explorer will give you a list of tags on the object, and tell you there are too many to show (which isn’t really true). If you then click ‘Load all tag values’ it will get them and show them to you.

• You can use my python library fdb, which has a command line tool with it and type:

  fdb show -q 'miro/bestsellers-1998-2010/rank = 1' /miro/bestsellers-1998-2010/title /miro/bestsellers-1998-2010/author

  This produces the following output:

  1 object matched
  Object e7fee95f-4dcd-458b-8893-b56352d455cf:
    /miro/bestsellers-1998-2010/title = "The Da Vinci Code"
    /miro/bestsellers-1998-2010/author = "Dan Brown"

• You can use curl at the command line (which is a utility installed on most systems by default) and type

  curl 'http://fluiddb.fluidinfo.com/values?query=miro/bestsellers-1998-2010/rank=1&tag=miro/bestsellers-1998-2010/title&tag=miro/bestsellers-1998-2010/author'

  which produces:

  {
    "results":
    {
      "id":
      {
        "e7fee95f-4dcd-458b-8893-b56352d455cf":
        {
          "miro/bestsellers-1998-2010/author": {"value": "Dan Brown"},
          "miro/bestsellers-1998-2010/title": {"value": "The Da Vinci Code"}}
      }
    }
  }
  

  (I’ve reformatted this slightly, but otherwise this is the exact output from FluidDB.).

• You could even just use the query directly in your browser’s URL bar. Pasting the following into the address bar should work in almost all browsers

  http://fluiddb.fluidinfo.com/values?query=miro/bestsellers-1998-2010/rank=1&tag=miro/bestsellers-1998-2010/title&tag=miro/bestsellers-1998-2010/author

  again, producing:

  {
    "results":
    {
      "id":
      {
        "e7fee95f-4dcd-458b-8893-b56352d455cf":
        {
          "miro/bestsellers-1998-2010/author": {"value": "Dan Brown"},
          "miro/bestsellers-1998-2010/title": {"value": "The Da Vinci Code"}}
      }
    }
  }
  

  In quite a few browsers, even the following will work:

  http://fluiddb.fluidinfo.com/values?query=miro/bestsellers-1998-2010/rank=1&tag=miro/bestsellers-1998-2010/title&tag=miro/bestsellers-1998-2010/author

2. More interesting queries¶

Regular readers of this blog will recall that I previously published a rather larger set of 1,000 books to FluidDB. These were again originally from the Guardian (though pre-dated the data store/data blog) and this time consisted of the the Guardian’s 1,000 novels that everyone must read. (See this post and this post for details.)

So an obvious question is: which of that original Guardian 1,000 books are in the 100 bestsellers of the last 12 years? The following FluidDB query will tell you:

has miro/books/guardian-1000 and has miro/bestsellers-1998-2010/title

(If I’d picked my tags better, this query would have been even simpler, but it’s not bad.)

As an illustration, if I issue that query, again asking for author and title, I get the following (using fdb):

fdb show -q 'has miro/books/guardian-1000 and has miro/bestsellers-1998-2010/title' /about /miro/books/title /miro/books/author

  /fluiddb/about = "book:the time travelers wife (audrey niffenegger)"
  /miro/books/title = "The Time Traveler's Wife"
  /miro/books/author = "Audrey Niffenegger"

(I’ve added some blank lines, but otherwise this is the raw output from fdb.)

Or perhaps I’d like to know all the books that sold over 2,000,000 copies. For that, the relevant FluidDB query is just:

miro/bestsellers-1998-2010/volume > 2000000

Again, illustrating with fdb, and this time asking only the for the about tag that FluidDB uses to identify the object, we get this (faintly depressing) list:

 fdb show -q 'miro/bestsellers-1998-2010/volume > 2000000' /about8 objects matched

3. Combining Data Sources¶

One of the things that is really interesting about this example is to look at the seven books that overlap. For example, Audrey Niffenegger’s wonderful book, The Time Traveller’s Wife is on both lists. A core idea of FluidDB is that different information comes to be associated by being placed on the same FluidDB object. The about tag (fluiddb/about) can be used to choose the object. In the case of novels, that object is identified [1] by an about tag of the form book:title (author)—in this case, book:the time travelers wife (audrey niffernegger). Obviously, there’s room for ambiguity with case and punctuation etc., but there’s a library and a website that will sort most of that out for you.

When I uploaded data on the Guardian 1000 books, (as the miro user) there wasn’t all that much information—author, title, year and the fact that it was on the Guardian 1000 list is pretty much all that was there. For example, here is what Aldous Huxley’s Brave New World looks like:

(Live version here)

In the case of the best-sellers, the dataset contained a bit more information including sales volume, publisher, average selling prices and total sales value.

The marvellous thing is that books that are on both lists automatically get all the data from both sources, simply because they both chose the same FluidDB objects (e.g., the one with the about tag book:the time travelers wife (audrey niffernegger), which you can see live here in a modern browser), or as it is at the time I write:

When I published the second list, I found that it included books that I had already rated in FluidDB. For example, I had already (personally, as njr) rated Small Island, by Andrea Levy, and as a result, when (as the miro user) I published the list of bestsellers, my njr/rating was already on some of them.

I think this is a powerful example of the potential of FluidDB, one that would be even more potent if it had been someone other than I (albeit as Miró) who had published to the at least one of two lists previously. But the point is, anyone following the convention about where to put data about books in FluidDB could equally easily have published the data with the same result. As usage of the system increased, we will see this more and more.

Go Explore; Go Tag¶

This post just scratched the surface, but I hope it begins to show the real and tangible benefits of publishing data to FluidDB. The data becomes capable of being queried. Multiple data sources combine, sometimes in ways that had not been foreseen. It can be accessed visually, from a command line, or programmatically. And you can add your own data, whether it be annotations, ratings, comments, associations or whatever.

So go explore; and if you like, get an account and start tagging/publishing.
