For .NET Framework tools to function properly, you must set your Path, Include, and Lib environment variables correctly. Set these environment variables by running SDKVars.bat, which is located in the \\Bin directory. SDKVars.bat must be executed in every command shell.

Xsd.exe only allows you to manipulate XML schemas that follow the XML Schema Definition (XSD) language proposed by the World Wide Web Consortium (W3C). For more information on the XML Schema Definition proposal or the XML standard, see

By using the /parameters switch, you can specify a single XML file that sets various options. The options you can set depend on how you are using the XSD.exe tool. Choices include generating schemas, generating code files, or generating code files that include DataSet features. For example, you can set the element to the name of an executable (.exe) or type library (.dll) file when generating a schema, but not when generating a code file. The following XML shows how to use the element with a specified executable:

To generate a code file, use the element. The following example generates a code file. Note that two attributes are also shown that allow you to set the programming language and namespace of the generated file.

You can also control how DataSet code is generated by using the element. The following XML specifies that the generated code uses DataSet structures (such as the DataTable class) to create Visual Basic code for a specified element. The generated DataSet structures will support LINQ queries.

There are attributes that you can set on the top level element. These options can be used with any of the child elements (, or ). The following XML code generates code for an element named "IDItems" in the output directory named "MyOutputDirectory".

We have this json schema draft. I would like to get a sample of my JSON data and generate a skeleton for the JSON schema, that I can rework manually, adding things like description, required, etc, which can not be infered from the specific examples.

What I want is something similar to this. The JSON data can provide a skeleton for the JSON schema. I have not implemented it yet, but it should be possible to give an existing JSON schema as basis, so that the existing JSON schema plus JSON data can generate an updated JSON schema. If no such schema is given as input, completely default values are taken.

json-schema-generator is a neat Ruby based JSON schema generator. It supports both draft 3 and 4 of the JSON schema. It can be run as a standalone executable, or it can be embedded inside of a Ruby script.

For the offline tools that support multiple inputs, the best I've seen so far is I'd like to see a tool that takes filenames on standard input because I have thousands of files. However, I run out of open file descriptors, so make sure the files are closed. I'd also like to see JSON Schema generators that handle recursion. I am now working on generating Java classes from JSON objects in hopes of going to JSON Schema from my Java classes. Here is my GenSON script if you are curious or want to identify bugs in it.

The XML Schema Definition tool (Xsd.exe) allows you to generate an XML schema that describes a class or to generate the class defined by an XML schema. The following procedures show how to perform these operations.

The tool can only process schemas that reference the World Wide Web Consortium XML specification of March 16, 2001. In other words, the XML Schema namespace must be " ", as shown in the following example.

Modify the classes with methods, properties, or fields, as necessary. For more information about modifying a class with attributes, see Controlling XML Serialization Using Attributes and Attributes That Control Encoded SOAP Serialization.

It is often useful to examine the schema of the XML stream that is generated when instances of a class (or classes) are serialized. For example, you might publish your schema for others to use, or you might compare it to a schema with which you are trying to achieve conformity.

The Schema Subset Generation Tool (SSGT) enables you to search and explore the content of the NIEM model. Additionally, you have the option of building XML Schema subsets of a NIEM release for use in NIEM XML exchanges. Based on the list of components selected by you for the subset, the tool will calculate dependencies and generate a valid set of schemas that are a subset of a release for download as a zip file.

A NIEM subset will contain only the user-selected elements and types from a release, plus any required dependencies. The subset will likely be much smaller than the corresponding full NIEM release (the 5.0 release has 12,000+ elements) and easier to deal with in an IEPD.

The Schema Subset Generation Tool (SSGT) search function allows you search and navigate through the various NIEM properties, data types, namespaces, codes / facets, and their relationships to each other.

The properties and types displayed in the search results are hyperlinked to display more detailed information about each component. This helps users navigate through the data model and explore the model hierarchy.

Some additional information about properties and types may be viewed directly from the search results list. Detailed information will be available by clicking the links to open the individual property info pages and type info pages.

Clicking on a property link will take you to a page with more information about that property. Commonly available information includes the definition, the type of the property, and any types that the property may be contained in.

The SSGT allows you to pick and choose specific parts of a release to include in a subset. This subset, which will likely have many fewer files and components than the full release, can be used in your IEPD. While you can reuse a full release package, it is easier to understand and work with only the schemas and the components that you need.

When building a subset, you may add elements, attributes, and types directly from the search results page, or from the property and type pages. All components in your subset will appear in the subset list on the left side of the page.

If you add property nc:Person to your subset, the SSGT will also add type nc:PersonType to your subset as well since it is a required dependency of the property. If you later remove nc:Person from your subset and no other component needs it, nc:PersonType will be removed as well.

In order to add an element or attribute to a subset as a sub-property of a type, this relationship must be captured explicitly. The SSGT will not do this automatically. Many properties belong to more than one type; other times a property may be added to a new type in an exchange.

Subsets also let you constrain how many times an element may appear nested within a type. As a reference model, NIEM usually sets cardinality to optional and over-inclusive (minOccurs="0" maxOccurs="unbounded") to support a wide variety of requirements.

In an exchange, you can customize the cardinality to your exact requirements. Make elements required, limit occurrences to only once, or set any other cardinality as long as it does not conflict with the original cardinality from NIEM (an element that is required in NIEM cannot be made optional in a subset).

This action affects only the designated type. It is not recursive. Any new type added to the subset through this action will be added empty. Users will need to add additional sub-properties to as needed.

When search results display a list of types, types can be added to the subset directly by clicking their Add buttons. This is useful for when NIEM does not have an exact match for a data requirement, but has a type that can be used directly, extended, or augmented in an IEPD.

The SSGT does not have the capability to migrate a subset from one release to another. This functionality only exists in the Migration Tool. Any subset in progress will be automatically deleted if you switch to a different release.

There is typically no need to view or use the wantlist schema. It is provided here for those who choose to build wantlists with another tool and use the SSGT only to calculate the dependencies and generate the subset schemas.

I keep getting the following error when reading a half dozen small Excel workbooks using a Data Input tool set to read *.xlsx from a specific folder. I have checked the Excel worksheets for format differences (header/footer, column headers, hidden columns, etc) and cannot find what is different if anything. I have even entered the scores from one survey response worksheet to the one that works and renamed/saved - still to no avail. I'm am definitely pulling my hair out over this one.

Anyone seen something weird like this occur before? Thoughts about how to troubleshoot? I have to process a fairly large number of worksheets in te next day or so. Open to any and all ideas... Thanks.

The schema also looks for changes in field type/size, not just name. That is typically the source of the error you posted. To avoid this error, you could build a batch macro where the control parameter updates an Input tool, rather than using a Dynamic Input tool.

You could use 2 input data tools loading the 1st file and you file in question and then attach a field info tool to each to compare the fields and datatypes of both. If it's too difficult to compare visually, you can use a join tool to highlight the differences.

pt-online-schema-change emulates the way that MySQL alters tables internally,but it works on a copy of the table you wish to alter. This means that theoriginal table is not locked, and clients may continue to read and change datain it.

pt-online-schema-change works by creating an empty copy of the table to alter,modifying it as desired, and then copying rows from the original table into thenew table. When the copy is complete, it moves away the original table andreplaces it with the new one. By default, it also drops the original table.
