Η Βικι-επιχείρηση: Καρτ ποστάλ αποτελεί μια προσπάθεια συντονισμού για την υποστήριξη και βελτίωση της Κατηγορίας:Καρτ ποστάλ, συμπεριλαμβανομένων των αρχείων και των κατηγοριών σε αυτήν. Οι καρτ ποστάλ αποτελούν πολύ καλή πηγή για τα Wikimedia Commons. Απεικονίζουν το παρελθόν και είναι χρήσιμα για την οπτική υποστήριξη πολλών λημμάτων της Βικιπαίδειας. Η προσθήκη εικόνων καρτ ποστάλ στο Wikimedia Commons θα μπορούσε να γίνει ένας εξαιρετικός τρόπος για τη δημιουργία της μεγαλύτερης συλλογής στην ιστορία της Δελτιολογίας. Μέχρι σήμερα έχουμε αναρτηθεί πάνω από 300.000 καρτ ποστάλ. Μαζί μπορούμε να φτιάξουμε και να οργανώσουμε αυτό το τεράστιο αρχείο. Αν σας αρέσουν οι καρτ ποστάλ, ελάτε μαζί μας και βοηθήστε στη δημιουργία αυτού του αρχείου. Αυτή η σελίδα προσπαθεί να θέσει πρότυπα για την καθημερινή εργασία.

Πνευματικά Δικαιώματα και Καρτ ποστάλ

Τα καρτ ποστάλ δεν είναι ελεύθερα πνευματικών δικαιωμάτων. Μερικές φορές ο κάτοχος των πνευματικών δικαιωμάτων (ο δημιουργός ή ο εκδότης του καρτ ποστάλ) τα παρέχει ελεύθερα δικαιωμάτων, όπως για παράδειγμα ο δύο που ακολουθούν Κατηγορία:Brück & Sohn ή Κατηγορία:Curt Teich.

Πολύ παλαιά καρτ ποστάλ

Is the postcard old enough (>120 years) you can digitize it and upload under a free license:

{{PD-old-assumed}} - over 120 years old (2023: Category:1903 postcards)
{{PD-old-auto-expired}} - if you know the year of death of the author

Ψηφιοποίηση και ανάρτηση

Ο καλύτερος τρόπος

Use a scanner or a camera to digitize your postcards.
Use TIF-format, because it has no compression artifacts. JPG-format is the second best choise. Experts upload TIFs (see example).
Digitize both sides, because some times many pieces of information are on the rear side (adress-space) of the postcard (title, publisher, date, etc). Use scanners with Duplex automatic document feeder (DADF, without bending the original)
Use highest DPI as possible. 600 dpi is a good choice. You never know what other users will do with the image you will upload. In the future they might become Wallpapers, for example.

Best practice: other versions = Image of address side
Best practice: other versions = Image of image side, Category:Address sides of postcards
Not so good: both sides in one image; difficult to handle and categorize, See also Category:Images with both sides of a postcard
Very bad: overwriting images with other side (see version history); difficult to handle and categorize, Category:Postcards with the other side in the page history

Ανάρτηση

For uploads of few postcards you can use the page Commons:Upload. This is the default way.
If you want to upload many more postcards, then you should test Commons:Pattypan. This tool scans a folder at your computer and generates a table, which will be saved in a spreadsheet-file. Afterwards, and offline, you could fill out this table with all metadata, using your office tools (Libre Office, MS Excel, ...). When this work is completed, Pattypan can be used to load the table and upload all images from your folder together with their metadata. For example all 590 images of the Category:Postcards by Erwin Spindler were uploaded this way.
If you want to upload a huge number of postcards, the tool Commons:VicuñaUploader is very good. For example over 30.000 images of the Category:Postcards published by Brück & Sohn were uploaded in this way. Normally, you should start the program and generate a session and upload the files, edit the metadata, and upload the whole work. But you can also save your session as a XML-File. This XML-File can be used as API for a big upload. Maybe you store all data of our postcards in a database you can generate an XML-file in this Vicuña-format and upload so a huge number of postcards in Commons.

For more information see Commons:WikiProject Postcards/Upload.

Metadata

Κατηγορίες

Every postcard should have at least one category of the subcategories of the Category:Postcards. If you find an postcard-image in Commons which does not include any of these Postcard-Categories, please categorize it. It will be very useful to set as a minimum:

a category of location (like Category:Postcards of Paris) or
a category of subject (like Category:Postcards of elephants)

Σημειώσεις

With the Gadget ImageAnnotator we can add notices to an image in Commons. This is very useful. First we can describe better what we see. Look at this postcard with over 10 annotations. Or we can add a notice for what we can read but we don't know the right category. Look at this image with the notice "Die Haubenlerche". If you search in commons for this text everybody will find this image.

Αριθμοί καρτ ποστάλ

Οι περισσότεροι εκδότες καρτ ποστάλ ενσωματώνουν στην εμπρόσθια ή την πίσω όψη των καρτ-ποστάλ τους ένα σειριακό αριθμό. Οι αριθμοί αυτοί διευκολύνουν στην παραγγελία της συγκεκριμένης καρτ ποστάλ.

Best practice

We could use this number in every image of its category in the following way, so that images are sorted by their serial numbers:
[[Category:Postcards published by Stengel & Co.|#:::::45231]]
We can, thus, easily check for double-numbered postcards or missing ones. Attention; if it is a 5 digit serial number we need five time ":".
For example see in: Category:Postcards published by Stengel & Co.

Second best

The second best choice is to write this serial number in the first part of the filename like in:
Example see in: Category:Images from Brück & Sohn

Search images with the property "serial number" (P2598) and value "Berlin 1 138" (Serie "Berlin 1" Number "138")
Attention: If you set a new structured data in an image, then it need a little bit time before you can search it with this query.

Add structured data to postcards

One of the best help for this project is to add structure data to the postcards. Here you find many to do:

To do list

Μπορείτε να βοηθήσετε

Insert in all postcards good categories.
Insert in all postcards Structured data (SDC), like Depicts. So we can use this for future sorting and processing scripts.

Current work (in progress)

Restructure the publisher categories
We create for every publisher like "Category:XYZ-Publisher" a "Category:Postcards published by XYZ-Publisher" as an sub-category.
For example: Category:Stengel & Co.
For example: Category:Postcards published by Stengel & Co.
Reason: So we can clean order all the postcards in this separate category. Many publisher publish also other stuff (images, posters, ...) not only postcards.
New: Every publisher get the Category:Postcard publishers and not like today Category:Postcards by publisher
Review Category:1900s postcards uploaded from Zeno
Upload from de.wikipedia over 1800 postcards from this de:Kategorie:Datei:Ansichtskarte

Logos of publishers

For better finding we start to fill the Category:Logos of postcard publishers.
So we can generate a gallery: Logos of postcard publishers.
If you don't know the publisher behind a logo, then insert the postcards with this unidentified logos at Category:Unidentified logos on postcards.

Γραμματόσημα

At the moment we have:

Category:Stamps on covers and postcards

Did we need a category for Stamps on postcards (only)?

Category:Stamps on postcards
Maybe this can help by the temporal classification.
- If the stamp is from 1930 then the postcard was sent in 1930 or later.
