When images are considered, those are storing their Meta data using different types of Meta containers such as EXIF, Adobe XMP, IPTC, Photoshop Image resource and Text descriptions. This every container has their specific unique rules to encode (store) and decode (extract) Meta data. As well as these each Meta container is storing specific Meta information. Exif Meta containers are mostly storing location information and GPS (Global Positioning System) records. As well as, Adobe XMP is responsible to store Dublin core Meta data which provides standard Meta tags that can be used to describe digital objects basically and IPTC is storing Meta information about application records. Meta data extractor is mainly considering these Exif, IPTC and adobe XMP Meta containers when it is extracting Meta data from images. As well as, these different Meta data containers are considered; they are structuring Meta tags in different dir...

In a previous blog, I explained How to add custom metadata using Syncfusion library. But this package gives so many difficulties when adding metadata to pdf. Such problems are,    1. When once add custom meta data to a pdf, it does not able to change or remove those custom meta data from the pdf.    2. It does not compatible with meta data search engines. It does not show custom meta data properly when those are searched through the search engines. Due to these reasons, Syncfusion is not good library for custom meta data. But, iTextSharp provides flexible framework to deal with custom meta data as well as standard meta data for PDF. Below I have provided the source code to show usage of iTextSharp library. You can download iTextShrp.dll from here                              PdfReader pdf = new PdfReader(input_path); ...

When You open MS Word Document pro-grammatically using 'Microsoft.Office.Interop.Word', you are creating 'winword' process. So after dealing with opened MS Word document  pro-grammatically though you close it using 'close' method, the 'winword' process is not terminating, it is still running on your OS. So you have to terminate it in the end of the program otherwise, it creates so many 'winword' processes for each time you open MS Word document and you may face to memory problems later.  You can use below code to kill 'Winword' process. foreach (System.Diagnostics.Process p in System.Diagnostics.Process.GetProcessesByName("winword"))             {                 if (!p.HasExited)                 {             ...

When we want to get the Created Date Meta Date from MS Document we can use ' DSOFile.SummaryProperties.DateCreated ' instance variable. This variable is given the date of file is originally created.                     System.IO.FileInfo file = new System.IO.FileInfo(@""+input_path);                     string creation_date = file.CreationTime.ToString(); This creation date does not mean originally created date of the document. For example, Consider I create MS Word document and save it in 'D' Storage of the memory and then I copy and paste it into MyDocument. Then the created date of copied document is considered as the copied time in above code. But, ' DSOFile.SummaryProperties.DateCreated ' is taking created date as the date of document originally created in Location 'D'

Here I use Syncfusion.Pdf.Base.dll to add custom meta data to PDF type documents. This DLL uses XMP based framework to define document properties for Adobe type documents. It is based on RDF which is W3C standard for XMP based Meta data. A dobe designed the st a nd a rd XMP schem a s. a mework permits the in tegr a tion of a ny schem a th a t is structured in a ccord a nce with the specific a tion. Some Examples for Adobe XMP Schemas   XMP Basic Schema   Adobe PDF Schema   Dublin Core Schema   Custom Schema      You can get more info from : http://www.pdfa.org/doku.php?id=artikel:en:pdfa_metadata          Now We Will See How To Deal with Meta Data using Syncfusion.Pdf.Base.dll First make a reference to particular DLL (Select & Right click on the project name in 'solution explorer' -> Add Reference ->  Browse -> Give the path of DLL) Then add this source code to code file ...
