Currently I am using Protege application to add classes, sub classes for the added classes and label for each subclass/class. I have many classes and I am really fed up adding many of these manually. I have got all of these classes, sub-classes and labels in a csv file. Each row contains these three things- class,sub-class and label separated by comma.
I would like to create OWL file with all these classes. Is there any way I could automate the process?
This use case seems pretty close to what a tool named Populous does. See its description here
Populous presents users with a table based form in which columns are constrained to take values from particular ontologies. Populated tables are mapped to patterns that can then be used to automatically generate the ontology's content. These forms can be exported as spreadsheets, providing an interface that is much more familiar to many biologists.
The table/spreadsheet format is equivalent to CSV, so easy to convert. The project is Open Source, so easy to reuse the code to achieve your target.
See http://www.populous.org.uk/ for more details.

I need to include a pdf into another pdf that is being created by text manipulation, not through a package. (In particular, I'm using livecode, which is well suited to the generation of the information I need, and can easily do text manipulation).
Once included, I will be adding additional objects (primarily text, but also a few small squares).
I only need to be able to access the included pdf by page and area, such as (200,200) to (400,400) of page 5; I don't need any access to its objects.
Simply appending to the pdf won't do the job, as I'll actually be including multiple source pdfs into a single pdf output with my addition.
I would like to simply make the original pdf an indirect object in the output pdf, and then refer to and use it. In particular, I would like to avoid having to "disassemble" the source pdf into components to build a new cross-reference table.
Can this be done? Or do I need to make new absolute references for each object in every dictionary, and to every reference to them? (I only need to be able to refer to regions and page, not the actual objects).
something that could be used on a one-time basis to convert an entire multi-page pdf wold also be a usable (but inferior) solution.
I've found that search engines aren't yielding usable results, as they are swamped with solutions for individual products, and not the pdf itself.
First of all, PDFs in general are not text data, they are binary. They may look textual as they contain identifiers built from ASCII values of words, but treating them as text, unless one and one's tools are extremely cautious, is a sure way to damage them.
But even if we assume such caution, unless your input PDFs are internally of a very simple and similar structure, creating code that allows to merge them and manipulate their content essentially is complexity-wise akin to creating a generic PDF library/package.
I would like to simply make the original pdf an indirect object in the output pdf, and then refer to and use it.
Putting them into one indirect object each would work if you needed them merely as an unchanged attachment. But you want to change them.
In particular, I would like to avoid having to "disassemble" the source pdf into components to build a new cross-reference table.
You will at least have to parse ("disassemble") the objects related to the pages you want to manipulate, add the manipulated versions thereof, and add cross references for the changed objects.
And you only mention cross reference tables. Don't forget that in case of a general solution you also have to be able to handle cross reference streams and object streams.
Or do I need to make new absolute references for each object in every dictionary, and to every reference to them? (I only need to be able to refer to regions and page, not the actual objects).
If you really want to merge the source PDFs into a target one, you'll indeed need to renumber the objects from most source PDFs.
If as a target a portable collection (aka portfolio) of the source PDFs would suffice, you might not need to do that. In that case you merely have to apply the changes you want to the source PDFs (by means of incremental updates, if you prefer), and then combine all those manipulated sources in a result portfolio.
I've found that search engines aren't yielding usable results
The cause most likely is that you underestimate the complexities of the format PDF. Combining and manipulating arbitrary existing PDFs usually requires you to use a third-party library or create the equivalent of such a library yourself.
Only manipulating existing PDFs is a bit easier, and so is combining PDFs in a portfolio. Nonetheless, even in this case you should have studied the PDF specification quite a bit.
Restricting oneself to string manipulations to implement this makes the task much more complex - I'd say impossible for generic PDFs, daring for PDFs of simple and similar build.
I am looking for a CATIA script to replace the names of all objects in the specification tree of a CATPart with a constant string suffixed by a running number. As an example, consider the following specification tree before renaming (left picture) and after the script run (right picture):
Background is the removal of sensitive information (such as part numbers of electronics components) for preparation of a STEP export of a large assembly.
Well this certainly is not a hard one to write and figure out. As I understand StackOwerflow is not a site where you get a code on demand but a site where you get help with your code.
I will give you a hint. What you are looking for are collections of objects which holds features, bodys, constrains etc. and iterate trough all these collections and change the names.
I would start recording macro when you manually change the names, then take a look at the script and learn from it.
I am tasked to create a template that will be Filled up by Business Users with Employee Information, then our program will load this into the Database using External Tables.
However, our Business Users constantly change the template by adding, removing or reordering fields.
I am convinced to use XLSX instead of CSV so that I can lock the Column Headers so they cannot remove, add and reorder the columns.
However, When i query the External Table, it shows Non-ASCII Characters when reading XLSX because its in Binary.
How can i do either of the following?
Effectively Read Excel Files from External Tables
Lock the Headers of CSV Files?
What you have here is a political problem, but you are looking for a technical fix. Not a good fit.
The problem comes in two halves:
Somebody decided it was a good idea to collect user input in a spreadsheet, which it is generally not.
Users are fiddling with the input format, which they should not.
Fixes are:
Strictly enforce the data structure. Reject any CSV which doesn't natch and make the users edit them. They will quickly tire of tweaking the spreadsheets when they realise they're just creating more work for themselves. But they will also get resentful, so consider ...
Building a data input screen. It's pretty simple to knock up a spreadsheet-like grid UI. You don't need anything complicated in Java: Oracle's Apex is intended for exactly this sort of thing. Find out more.
However, if you are stuck with Excel as a UI I suggest you have a look at Anton Scheffer's excellent PLSQL as_read_xlsx package on the Amis site. Check it out. You'll probably need to replace your external table with a view over a table (perhaps pipelined) function.
I have a dataset table with various columns that are created during form load.
These columns are currently either system.double or system.string types.
And it is displayed in a datagridview.
This works fine.
But I need another column that can store a "list" or some collection in the data table.
A list of strings would do but a custom class would be better.
How is this usually done?
I have spent literally weeks googling this and I dont know where to start. The more I have looked the more confused I have ended up. I end up with more questions than answers, like how is it displayed in the datagridview? I read about a combo box?
I hope someone can give me some pointers in how to get this achieved. I've not posted any code as I think its more the theory of this I need help with.
What you are asking for has does have multiple concerns for most programmers. The storage of data (#1) and the displaying of said data to the user (#2)
For #1 I recommend the .net entity framework. It gives support for storing, querying and updating classes for use in the database. Through most tutorials that I have found it is possible to model the structure of the database tables and their relations and then build a database around that model OR to use an existing database and create entities (entity framework's class objects) around the existing structures and relationships.
Here is a link to a very good beginner tutorial that I have used before: CodeProject Entity Framework Tutorial for Absolute Beginners
For #2 I can recommend the Windows Presentation Foundation. It has lots of bells and whistles to make using a data source and displaying the relevant dependent data very easily through its unique method of data binding. From the tutorials I have used on PluralSight it can be as easy as dragging and dropping from an imported data source like the entity framework database. Alternatively, one can just handle selected row changes for one data grid and then show the dependent data in another data grid.
I have many, (15-20) different XML files that I need to load to VB.Net. They're designed as they would be in a database; they're designed in Access and bulk exported into XML files. Each file represents a different table in the database.
Now, I need to load this information into VB.Net. Initially, I'd love to use DAO and access the MDB directly via queries, but this won't be possible as I'm making sure the project will be easily ported to XNA/C# down the road. (Xbox 360 cannot use MDBs, so I'd rather deal with this problem now than down the road).
So, I'm stuck now trying to figure out how to wrangle together all of these XML files together. I've tried using Factories to parse each one individually. E.g., if three XML files contain data for a 'character' class, i'd pass in an instance of Character to each XML factory and the classes would apply the necessary data.
I'm trying to get past this though, as maintaining many different classes with redundant code is a pain. plus it is hard to debug as well. So I'm trying to figure out a new solution.
The only thing I can think of right now is using System.Reflection, where I parse through each member of the class/structure I'm instantiating, and then using the names of those members to read in the data from that element of the XML file.
However, this makes the assumption that each member of the structure/class has a matching element in the XML file, and vice-versa.
If you know the schema of the XML files - you could create .NET classes that can deserialize one of those XML files into an instance of a .NET object.
You can also you use xsd.exe (comes with Windows SDK download) to generate the .NET class definition for you if you have an XSD file (or can write an XSD easier than you can write a serializable .NET class).
Linq-to-XML is a good solution (and even better in VB.NET with things like XML Literals and Global Namespaces). Treating multiple XML files as DB tables can be a rough road some times, but certainly not impossible. I guess I'd start with JOIN (even though it has "C#" in the title, the samples are also in VB)..
