metadata

Our of curiosity, is there a way to read PDF metadata -- such as the information shown below -- from R? I could not anything about that by searching from [r] pdf metadata in the current question base. Any pointers very welcome! I can't think of a pure R way to do this, but you can probably install your favorite PDF command-line tool (for example, the PDF toolkit, PDFtk and use that to get at least some of the data you are looking for. The following is a basic example using PDFtk. It assumes that pdftk is accessible in your path. x <- getwd() ## I'll run this example in a tempdir to keep things

Trying to get meta_data that i have set on all my items in an s3 bucket. Which can be seen in the screenshot and below is the code I'm using. The two get_metadata calls return None. Any idea's boto.Version '2.5.2' amazon_connection = S3Connection(ec2_key, ec2_secret) bucket = amazon_connection.get_bucket('test') for key in bucket.list(): print " Key %s " % (key) print key.get_metadata("company") print key.get_metadata("x-amz-meta-company") bucket.list() does not return metadata. try this instead: for key in bucket.list(): akey = bucket.get_key(key.name) print akey.get_metadata("company") 来源：

I want to store some metadata in images. My camera application gives me a bitmap, which I store in the storage (MediaStore) device. In addition to this, I want to add a few tags to the picture in its metadata. I think EXIF is a good way of doing this. But I couldn't find good references on how to do this. If there are some tools to achieve this task in Android programming, please let me know. Thanks Ok, Somebody (offline) pointed me to a useful resource. The ExifInterface looks like what I was searching for. Android-er has a post demonstrating how to read EXIF metadata in Android and I think

Say I have the following code: (defn ^{:graph-title "Function 1"} func-1 [x] (do-something-with x)) (defn get-graph-title [func] (str ((meta func) :graph-title))) I expect this to return "Function 1", but it returns nil. I think this stems from the following difference, which I don't totally comprehend: (meta func-1) => {:ns some-ns-info, :name func-1} (meta #'func-1) => {:ns some-ns-info, :name func-1, :graph-title "Function 1"} Can someone explain this to me? The metadata is attached to the var, not to the function. Thus, to get the graph title, you have to get the entry :graph-title from
