At the end of the process of saving the file, the icon      will appear indicating that the process has finished correctly.

 

In order to avoid the need of having to write all the time the same information in the different metadata fields, you can use the metadata templates. To do this, fill in the data you are interested in and click on the icon     to save it as a metadata template.

When you want to apply these values to a new file you just have to click on the icon      and the different metadata fields with the previously saved values will be automatically completed.

Metadata in Image Files

The main existing standards for the definition of metadata in digital images are: EXIF, IPTC and XPM.

EXIF is the metadata format most commonly used by digital cameras. It defines a series of tags, which describe the characteristics of the camera (manufacturer, model, software, etc.), and its configuration at the moment of capture of the image.

IPTC is a consortium formed by the main news agencies and communication companies. At IPTC, journalism organizations develop and maintain technical standards to improve and homogenize the exchange of news between the agencies of the world.

XMP is a standard that defines a model for the creation and processing of metadata, based on XML tags. This model uses a metadata schema to store basic properties, and another schema so that each device or application can store its own information. In this way, each application can use this common method to capture and share its metadata.

Some types of metadata are created and used exclusively by one of the standards. In contrast, other types of metadata are implemented by more than one standard.

MetaClean allows the treatment of stored metadata for each of these standards in a simple and intuitive way.

MetaClean allows Geo-Localize your images, for that, we will load the images in the main work area as it has previously been described, we will select the image and we will click on the button 

 

A new window will be displayed where in the “Direction” field and we will enter the address of the place where the photograph was taken, it is not necessary to know the exact address of the place, it is enough to indicate a reference of that place:

 

 

And then press the “ENTER” key or click on the button 

As you can see in the following image, all the location fields of the entered address will be automatically completed, showing also the location on a map that will allow us to zoom and even change its view.

 

 

To finish, we will save the GPS location by clicking on the button   

Considerations for Audio, Video and Images files:

  • Only those metadata that are modifiable will be eliminated or edited, there is a large number of metadata that are necessary for the different tools on the market to manipulate / visualize this type of files.
  • Metadata templates are not applicable to this type of files.

Also, MetaClean has several work shortcuts once the files are loaded.  In order to access to them we will place the mouse pointer over the area “files uploaded” and click with the right mouse button. A drop-down menu will appear that will allow us to choose between the following options: “Load files”, “Remove selected files from the list”, “Copy or move files to another directory”, “Export metadata”, “Open file location” or “Open file”, in a single click.

 

 

3.3 – Clear File and Clear File List

The options “Clear File” and “Clear File List” allow you to delete one or several files from the uploaded file list. But the files will never be deleted from the Operating System.

3.4 – Search files

This tool allows you to load the different files automatically, you only have to indicate the type of file you want to upload and the directory to look for (and if you want to search also in sub-directories).

 

When the search process finishes, the “Search for files” window will close automatically and the files found will be displayed in the main window.

 

 

3.5 – Search for Metadata

Search for Metadata allows you to search for files based on the content of each of the metadata fields. First you will have to select the type of file to be searched.

 

 

Then select the types of files to search (Word, Excel, …), the search directory and finally complete each of the conditions that must be met.

In this example, all PDF files are to be found in the directory C:\Carlos\personal\Adarsus (and sub-directories) whose metadata Author contains the string: cgonzalezg

 

 

When the search process finishes, the window “Search metadata in files” will be automatically closed and the files that meet the indicated conditions will be displayed in the main window.

 

 

Below you can find another example for searching multimedia files based on their metadata. In this case, we select the option: Image, Audio and Video Files.

 

 

We will search in the directory G:\Test Images (including sub-directories) all the images that have GPS coordinates and that the model of the camera contains the string: Nikon

 

 

 

3.6 – Organize files

The “Organize Files” option allows you to copy or change one or more files at the same time.

From the main window, select the files you want to move or copy.

 

And then click on the “Organize Files” button. The following window will appear where we will select the destination directory and the action (copy or move).

 

Then click on the icon       to start the operation.

For each of the documents, a message will be displayed that shows the result of the process: “File copied/moved successfully”.

 

If we combine the utility “Search by Metadata” with the utility “Organize Files” we could for example organize our photographs based on the date they were taken and then move them to a directory that indicates the corresponding trip.

For this we would indicate in the metadata          the date in which the photograph was taken and then we would move it to the desired directory.

Also, we could organize all our documents in different directories based on the content of their metadata (organize them by title or author of the document for example).

 

3.7 – Export Metadata

The option “Export Metadata” is designed to export the metadata of files of type: Microsoft Office, Open Office and PDF to an Excel or CSV file.

To do this, select the files you want to export and click on the “Export Metadata” button.

 

Next, a new window will be displayed where you will select the directory where you want to save the file with the exported metadata, choose the file type (CSV or Excel) and finally click on the process button

 

 

MetaClean will display a message for each processed file showing the result of the export. At the end of the process, a file called “Metadata-exported” will have been created in the directory previously selected that will contain the metadata of the selected files in the format previously selected.

In our example, we have selected an Excel file where we can see that the first columns identify the complete path to the processed file and its type, and then a column for each type of metadata.

In the exported file, a column will be created for each type of metadata that a document can contain:

  • Document title.
  • Subject of the document.
  • Author of the document.
  • Keywords of the document.
  • Date of creation of the document.
