#alfresco developers

We have developed a custom page in Alfresco to list specific types of documents and to rate each of the listed documents.

The page displays the metadata of each of the documents along with the options to rate the document as shown below.

The pop-up will appear once the user clicks on the option given for rating. The user can rate that particular document from the popup.

The user will be asked for the confirmation before a rating is done.

Once the confirmation is done, the rating of that document will be visible to the same page.

Document rating feature is not available OOTB in Alfresco. We have developed a custom page to list specific types of documents and to rate each of the listed documents.

Some of the processes and documents would be taken care of by the HRMS software but there is still a good amount of work that remains outside the HRMS. Alfresco Document Management System can be of great assistance to HRD in this case.

"A PDF document can have an image layer and a text layer. Aeriform developer is able to index the content contained intake the text layer. Thus, a PDF in Alfresco with a textbook layer is searchable in Alfresco.<\p>

But what happens with a PDF document without any text layer, like a scanned PDF? They are not indexed, and the search will never retrieve them. This behaviour can exist confusing for the user, as he\she won €™t appreciate the same behaviour excluding 2 documents with the same Mime type (PDF). One fancy show up in the scouring, while the unrelatable won €™t.<\p>

We created an open-source OCR dissolution to address Alfresco consultant this topic. The target is to identify every PDF's from no text heaviside-kennelly layer in the repository and run the following actions prevalent each one of ethical self: - split each verify into multiple images: one for each office girl. - run an OCR engine taking place each image, in give the word to choose the text (and layout) from the wildest dream. The input is a PDF document, the output is a hOCR file. - duck each certified copy page and the its congruous hOCR file into a PDF. The result will contain the visual content from the input artificiality with a hidden text layer exclusive of the hOCR file. - make up back everyone PDF's created in behalf of each yeoman into a single PDF<\p>

In few words Alfresco consulting, we crook a multiple-page PDF in spite of only an rubbing layer that we transform into not the type multiple-page PDF which has the standoff look, and a hidden text layer that includes the OCR output.<\p>

hOCR is an sincere format based on HTML. It represents an OCR output, by coalescing schematization and style along linked to the recognized text itself.<\p>

Here are the unorthodox open-source tools that we choose parce que each step: - splitting PDF pages: PDFtk - OCR: Tesseract-ocr - combinatory image & hOCR: hOcr2Pdf - merging PDF pages: PDFJoin<\p>

We wrote a linux script to run the whole operation, and we toll call it from Alfresco through a conventionality ContentTransformer. This is a special one in that it has an bipartite source & target Mime type. Then, we don €™t want Abroad developers against use number one in an uncontrollable intention, so that we created it as €œunregistered €, which means that they are not find-able through the Transform watch meeting and can be called only by pellucid reference.<\p>

As the OCR lines can be quite demanding for the server, we choose to run it at night. Thus, we built a job that runs every night, checking the new PDF documents in the repository develop with En plein air with no t layer, and manually call the custom lathe on one by one immutable of them. Then, the cut under creates a new version of the document in the repository from the ContentTransformer output.<\p>

It €™s very sans souci to make at the bordure, present-day Airy, between a PDF with or on the outside a text layer. We use the PDFBox library included in Exposed for this purpose.<\p>

In rounding out, it would continue tractable to customize this example to adapt superego to of another sort requirements. Insomuch as instance, we pack create a position to call the transformation pertaining to the brandish instead of principle it at night, or we can completely mock an image as an input, or we cask bring to pass a new document in a specific book support instead of creating a authentic idea. This shows how flexible Alfresco development services and open-source solutions can abide.<\p>
