[CEUR Workshop Proceedings (CEUR-WS.org)]

Publishing with CEUR-WS.org

This document is addressed to organizers of scientific workshops who are interested in distributing the proceedings of their workshops electronically.

Reasons to publish via CEUR-WS.org

We invite organizers of scientific workshops to use the WWW site
SunSITE.Informatik.RWTH-Aachen.DE/Publications/CEUR-WS (CEUR-WS.org)
as a medium to publish their proceedings. The service is part of the activities under the umbrella of SunSITE Central Europe. The goal of CEUR-WS.org is promoting information exchange within the academic community. We aim at a high-quality service with the following characteristics: Proceedings published on CEUR-WS.org are freely accessible on the SunSITE. Hence, there are no technical provisions (access authorization) to prevent un-authorized use of the proceedings contents.

Being freely accessible does not mean 'public domain', however. All material remains copyrighted.

How to publish

A crucial thing in publishing is to know who is the publisher! In CEUR-WS.org, you as proceedings editor are also the publisher. You submit the material on our FTP server (see procedure PUT below) and you can remove it (procedure DELETE). We just provide you with the publication tool, i.e., the WWW server of SunSITE.Informatik.RWTH-Aachen.DE. By default, we do not acquire any rights or responsibilities for the publication. You, the proceedings editor, are responsible for having acquired the exclusive or non-exclusive right for electronic publication for all published material (papers, possibly logos of companies) from the copyright owners, in particular the papers' authors. See here for an example how a copyright transfer form might look like (example kindly provided by Pedro J. Molina under GNU Copyleft licence). You can adapt it to your needs or create your own form. In any case, CEUR-WS.org is not keeping track of this part of your proceedings preparation.

The standard phrase defining the rights for readers of individual papers in a proceedings volume is

"Copyright © XXXX for the individual papers by the papers' authors. Copying permitted for private and academic purposes. Re-publication of material from this volume requires permission by the copyright owners."
where XXXX is the year of publication. This phrase tells readers of your proceedings volumes the conditions under which they can download individual papers (resp. material contained in your volume). Make sure that the rights you obtained from the paper authors are compatible with this phrase! You can also negotiate with us an adaption of the phrase. Be aware that CEUR-WS.org has no obligation to track copyrights violators. We, i.e. the manager of CEUR-WS.org and the organization that hosts CEUR-WS.org, take no responsibility for any damage caused by the publication of your proceedings volume. See disclaimer for more details. You are the publisher of your own proceedings volume, CEUR-WS.org is just a publication tool.

Formally, CEUR-WS.org (and the editorial board of Sun SITE Central Europe) is not obliged to store any submitted material on the server. In practice however, we are committed to provide this service for a virtually unlimited time. The published material must be scientific or serve academic purposes. It may not contain indecent parts or parts violating human rights. Commercial advertisements should be avoided. Better put them on the home page of your workshop.

A. Prepare the submission file

Before the PUT step, you prepare a submission directory containing all material to be published. This directory must contain at least a file named "index.html" which serves as the entry point to your material. The entry point "index.html" to your material shall conform to the CEUR-WS master layout. A good example is index.html of Volume 313. Depending on the structure of the proceedings, you might have sub-headings in the table of contents, for example like in index.html of Volume 296.

From the year 2008 onwards, we impose a soft restriction on the number of papers per proceedings volume. A normal volume should have at least five papers. If your proceedings volume has less papers, you should contact CEUR-WS.org in advance to get the volume published.

View the files as ASCII text rather than as HTML code. Your file index.html must at least contain the title of the material and the names/addresses of the editors (normally identical to the publishers). It must use the style sheet http://ceur-ws.org/ceur-ws.css which defines some common layout for proceedings volumes. It may not contain or start executable code such as Java, Javascript, Active-X or any other type of executable code. You can check the consistency/completeness of the submission directory by accessing it locally with your Web browser. Please do not use a Web page editor to produce index.html but rather a simple text editor like 'vi' or 'notepad'. Web page editors including MS-Office-WinWord tend to produce unreadable HTML code which we want to avoid in CEUR-WS.org. The FONT command should not be used unless for exceptional cases like a footnote or an acknowledgement. Special characters like umlauts and accents should be encoded in HTML by their command form, e.g ä for ä. Using 8-bit ASCII codes for such characters is likely to cause problems. Please be careful in the preparation of the file index.html. Delays in publishing a volume are mostly due to errors in that file. The management of CEUR-WS.org reserves the right for adapting the file index.html to accomodate the common style of CEUR-WS.org and to include volume numbers and similar meta information.

The technical papers in the proceedings should be in one of the following formats (ordered by preference):

Prefer neutral filenames like paper1.pdf over content-carrying filenames like SmithAndWagon.pdf. Strictly use ISO-compliant filenames and directory names! For example, ISO does not allow blanks in a filename like in "paper 1.pdf".

Local vs. absolute links

The links in "index.html" to the published material should be local, e.g.
  HREF="paper1.pdf"
rather than absolute
  HREF="http://www.dept.org/paper1.pdf".

Paper files and other items should be put in the main directory rather than sub-directories of the submission directory. This allows short URLs to the citable items of a published proceedings volume. An exception to this general rule are back links to workshop home pages and home pages of scientific institutions (or research labs) sponsoring the workshop. Moreover, back links to editor and author home pages are welcome. Please note however that such absolute links can and will become dangling when people change their affiliation! That's also a reason why putting the proceedings online at CEUR-WS.org is probably a better idea than putting it on your home page.

We advise proceedings editors to include a link to their workshop web page in their index file of their CEUR-WS volume. This allows readers to easily locate further information about the workshop such as the call for papers. We also recommend to include a back link from the workshop page to the CEUR-WS volume.

LaTeX optimizations for PDF

If the papers are prepared by LaTeX 2e or LaTeX 2.09 and converted to PDF format, then the fonts might look ugly since they are represented as bitmaps. Most LaTeX installations contain alternative Postscript fonts which result in much more readable PDF files. Please try the following settings directly behind the documentclass command with LaTeX 2e:
  \usepackage{times,latexsym}  % use Postscript font instead of TeX times and math fonts
If you are using the older version LaTeX 2.09, then the Postscript fonts have to be configured in the first line, e.g.
  \documentstyle[times,latexsym]{article}
Note that some LaTeX installations do not include Postscript fonts. Then you cannot use the above optimizations for PDF. Other text processors like StarWriter and MS-Word produce Postscript files that can be converted to readable PDF without the abovementioned font problem.

Images in HTML files

If your proceedings volume contains images, then you should prefer PNG (portable network graphics) over other formats like GIF. The GIF format is not free for all purposes and is therefore not suitable for free information services like CEUR-WS.org.

How to deal with page numbers

In many cases, authors are interested that a published proceedings volume contains information about number of pages of their paper. Such data is typically used for evaluating the research output of academic staff. It can also be used to indicate the length of an article in a reference. While CEUR-WS.org does not require you to supply such data, you might be interested in how to deal with this.

One way is to deal with page numbers is to assign them local per paper, e.g. paper 1 has pages 1.1 to 1.14, paper 2 has pages 2.1 to 2.15, and so forth. An example is shown in Vol-19. You should in this case inform the author about their paper number so that they can produce the right page numbering of their final paper version.

If you want to supply absolute page numbers, then you need to produce an integrated proceedings document like for example in Vol-62 and include the page numbers from the integrated proceedings document. Absolute page numbers are preferable but they also require much more work on your side.

Most volumes in CEUR-WS.org have no data about page numbers. So, providing them is an extra service. We have no specific knowledge about suitable tools to change page numbers or merge multiple pdf files into a single one. You might want to try Pdftk, Adobe Acrobat or CutePdf.

If you want to merge several pdf files into one and create a table of contents for the merged document, you may want to use the LaTeX macro definitions by Daniel A. Sadilek, originally used for producing the aggregated proccedings file Vol-324/dsml08.pdf.

Creating the submission file

As soon as your submission directory is ready you should pack it into a single submission file. The submission file should be prepared by the UNIX command
 zip -r sub_file.zip dir_name
where "sub_file.zip" is the name of the submission file and "dir_name" is the name of the submission directory. For example, the command
 zip -r  IBDD96.zip IBDD96
creates a submission file for the material contained in the directory IBDD96. Use meaningful names for the submission file, e.g. the acronym of the workshop. Under Windows, you can use packers like WinZIP, PKZIP or similar to produce the submission file. But beware: use ISO-standard file names! In particular, blank characters in file names are not allowed. Under Unix, you may also use the 'tar/gzip' commands to create the submission directory. Make sure that the submission file expands to a directory and not to files in the current directory. Subsequently, the procedures PUT (submit a proceedings volume to be published on CEUR-WS.org) and DELETE (remove a published volume) are explained. These two procedures shall be executed by one of the proceedings editors., i.e. by you. You should in particular sign the corresponding fax, and you should be the person mentioned in the clause "submitted by ..." at the end of the index file of the volume. If you are one of the editors but the technical upload is done by a person who is not one of the editors, then you should use the clause "submitted by your name, other name" in the index file.

B. Procedure PUT

  1. Make sure that you have the exclusive or non-exclusive right to publish the material you are going to submit.
  2. Read the legal disclaimer of Sun SITE. If you don't agree then do not procede.
  3. Print the PUT FAX form, fill it out, and sign it. Send the FAX to +31-13-466-3069 on the same day when you transfer the submission file.
  4. Transfer the submission file via http://ceur-ws.org/bscw-upload.html.

Use proper document names for the submission file like ibdd96.tar, ibdd96.tgz or ibdd96.zip depending on the archiving program you use. ZIP format is preferred.

Step 3 (sending the PUT-FAX) should be executed before step 4! If you do not have access to a fax machine, you may send the signed PUT-FAX via postal mail and send a scanned image via email to shortcut the transport time of the postal mail. The PUT-FAX has no direct legal role for us. It just indicates us that you are aware of copyright issues. If the material is accepted by us you will receive a notification with the bibliographic reference of the material.

Some proceedings editors would like to get a CEUR-WS volume number assigned to their workshop in advance to the publication at CEUR-WS, for example to announce it on the workshop web site or to include the URL of the proceedings volume in the impressum of the proceedings. To do so, just contact the manager of this site via email (see end of this page) and specify a deadline until which the proceedings volume will be uploaded. It is not a requirement to ask in advance for a volume number. Neither do we recommend to ask for a volume number in advance. The standard procedure is that we assign the next free volume number to your proceedings as soon as you upload the submission file and send the accompanying PUT FAX.

C. Procedure DELETE

You may remove your proceedings from our server at any time, even without telling us the reason. A reason could be that you want to publish the proceedings as a book and the publisher requests exclusive copyright for that. Note: this holds for proceedings editors but not for authors of individual papers. We will not remove individual papers from published proceedings. Only complete volumes can be removed. You should make the authors of papers aware of this rule.
  1. Print the DELETE FAX form, fill it out, sign it, and send it to the fax number +31-13-466-3069
CEUR-WS.org is only responsible for removing the specified proceedings volume from its own site. Copies of the volume published elsewhere are outside the scope of CEUR-WS.org and will not be removed upon reception of a DELETE-FAX! This is true in particular for services which scan the Web for online papers and make copies of the papers available in their own site. Examples of such services are Citeseer and scholar.google.com. CEUR-WS.org has no legal relationship with any such organization. We neither authorize nor track their activities wrt. papers published on CEUR-WS.org.

The actual date of execution of PUT/DELETE is subject to local maintenance policy of SunSITE.Informatik.RWTH-Aachen.DE.

How to correct errors in an already published volume

First of all, be careful in preparing the submission file in order to avoid errors! Ask a colleague to double-check, i.e. that all paper files are included with the correct file names and that all author names and paper titles are correct. When an error still slips through, you should upload a corrected version not later than 4 weeks after the publication date via the method described above (extra fax not necessary). Please first download the published version of your proceedings from
  ftp://sunsite.informatik.rwth-aachen.de/pub/publications/CEUR-WS/Vol-XXX.zip
and then make the changes as required.

Clearly indicate in the revised index.html the correction date and possibly the kind of revision you made, e.g. at the end:

23-Aug-2007: corrected title of paper 3
Afterwards, put the corrected proceedings volume into a zip archive Vol-XXX.zip and upload it as described for the PUT procedure. Notify me with an email that you uploaded a correction.

The revision of published volumes is limited to error correction! For example, it might be that you forgot to include the pdf file of an article referenced in index.html. Another example is a misspelled title or author name. The revision is not meant for providing any improved version of a paper or to include papers that were not originally intended to be in the proceedings! Likewise, you cannot remove individual papers that were included in the original proceedings submission. This would violate the unwritten rules of academic conduct.

Of course, you as the proceedings editor have the right to remove a proceedings volume as a whole (see procedure DELETE above).

Re-publication vs. mirroring

Being freely accessible on the Internet does not imply an automatic right to re-publish/re-package CEUR-WS.org proceedings volumes (or parts of them) without authorization. Normally, only the proceedings editors have the right to re-publish their proceedings elsewhere, e.g. with a publisher or via a Web site. When proceedings editors decide to re-publish their CEUR-WS.org volume elsewhere, they should make sure that the re-published version is clearly distinguishible from the CEUR-WS.org version. In particular, it may not use the following attributes characteristic to CEUR-WS.org:

Authors of individual papers are not restricted by CEUR-WS.org to re-publish their papers elsewhere. In fact, CEUR-WS.org does not acquire rights from authors: authors pass rights to the proceedings editors. This is typically a non-exclusive right to publish the author's paper. By doing so, authors can of course no longer publish their papers with another publisher who demands the transfer of the exclusive copyright! This would violate the earlier transfer of non-exclusive copyrights to the proceedings editors.

We forbid mirroring of the CEUR-WS.org web site or its parts. Mirroring is different from re-publication since it publishes a one-to-one copy via another Web site. A mirror would negatively affect the authenticity of CEUR-WS.org. At the end, why would anyone want to have a mirror of something that is freely accessible anyway?

How to reference papers published via CEUR-WS.org

A paper in a CEUR-WS.org volume should be referenced using its online URL, for example
   M. Lenzerini: Description logics for schema level reasoning in databases.
   Proc. of 1st Workshop KRDB'94, Saarbrücken, Germany, September 20-22, 1994,
   CEUR Workshop Proceedings, ISSN 1613-0073, online CEUR-WS.org/Vol-1/lenzerini.pdf.

A shorter form can be:
