Dc:format Types Dam content files

[hari_prasadp686]

Hi,

i am doing search based on dc:format type on DAM folder.

When we uploading the file to the dam content multiple dc:format types are generating for same type of documents but different format types . 

Example : Excel file 

1. *.xls is the one file format type

2. *.xlsx is one more format type of Excel file.

for these two format types dc:format types are different. but both are excel files only. 

and few of old version doesn't have the dc:format types. Example : 2003 version word of MS word and PPT files. format types are *.doc and *.ppt.

can you please explain any, one why AEM having this features with multiple things. 

Thank in advance, if any one explained.

dc:title is filled according to the mime type of the file, and according to the standard, xls and xlsx are different mime entries.

.xls      application/vnd.ms-excel .xlsx     application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

This will be similar for .doc and .docx, ppt and pptx etc.
