Find your document in the document library, click on the title (that will display the document) then at the bottom right you will see the metadata. To edit it, click "Edit [properties".
rjohnson, thanks for answer. But i need to run my program by clicking "ok"(finish-button) button on the property sheet. And this program need to access to new posted metadata.
One way would be to create a rule on the relevant folder(s) that is triggered when a document is added or updated. In this code you can then iterate through the metadata in a variety of ways using document.properties. document.properties is a associative array of the metadata so you can do a for each through the keys and then indirectly access each array element. You can then build the data into a suitably formatted csv string and append this to a document in Alfresco or you could write it to an external file (but that would require a java bean).
There is an example of appending data to an Alfresco document in the javascript cookbook (which is on-line) its in the "Create a backup of a document" section if memory serves.
You can then open your csv document in Excel.
If you wrote the java bean to write to an external file then you could write directly into Excel format if you used the Apache POI libraries.
