I am new to this forum. Few days back i configured alfresco in our office. We have 2500 images in one folder and each file name having 20 tags in excel file.
Is this possible upload all the files and read the tags from excel file.
Well out of box it is not possible but you can certainly write a webscript which can serve your purpose.In webscript you can upload those images one by one and during upload you can attach those tags by reading that excel file. And you will require Java backed webscript you can find sample scripts over here http://wiki.alfresco.com/wiki/Java-backed_Web_Scripts_Samples
Reading the tags from the Excel file might be the tricky part (although I've not got much experience with it)… although it might be easier to export the Excel spreadsheet contents as a CSV file as that would undoubtedly be easier for a WebScript to work with.
