Automated document processing and numbering
Simplify acquisition of basic metadata for new documents
Automating the initialization of all possible metadata for new documents ingested into a content repository is a critical feature that brings various benefits, including:
- Reduce workload for the users
- Eliminate error-prone manual activities, such as generating and assigning unique identifiers
- Guarantee that the basic classification of new documents is performed upon initial creation, avoiding the presence of unclassified documents in the repo
A possible, lightweight approach to the problem, described below, includes adding background listeners to the target repository containers. Once new documents are added, a tailored Content Script routing will apply all necessary rules to identify the documents, and generate or extract the required metadata.
Adding documents to a controlled folder
Let's start from a Content Server container (in our case, a simple folder): a Content Script Callback has been set up to intercept the creation of new documents within this space. This means that any time one or more documents are dropped (or otherwise loaded) into the folder, the callback script is executed and the custom business logic applied to each object.
In our example, the callback script performs the following actions:
- generation of a unique identifier (document number) for the new document
- extraction of metadata directly from the document
- extraction of information from the context of the operation
- renaming of the document to ensure uniqueness within the space
Specifically, the extraction of information from the document can be very powerful as there are many interesting possibilities, enabled by the variety of Content Script APIs available.
A basic operation can be to extract information from the file name. This could be done in a very straightforward way (e.g. use the file name as the document "Title") or in a more creative way (e.g. extract an invoice ID based on a predefined pattern)
One step further could be to access properties specific to the type of document. For example, MS Word or Excel documents include a built-in "Title" and "Author" property. Content Script APIs include tools to access the files and read this data, as shown below.
A step further in terms of complexity could see you combining the integration and communication capabilities of Content Script with data available directly on the document. For example, once the invoice ID is identified by decoding the file name, an service call can be executed to fetch additional details from the ERP system.
In any case, once done, the new documents will be available within the store, and the processed metadata directly accessible.
