rdf semantics

With the popularization of web standards in China, the concepts of structural performance separation, modularity, semantics and elegance degradation have also become an important part of the understanding of Web standards by a front-end staff, among which, because of the impact of the commercial value behind the SEO, "semantic" has been highlighted, As an entry-level front-end worker, I have simply argued that "semantic" is the way to use the tag orga

I attended a WD training organized by the company two days ago. One Class talked about tag semantics. After listening, I felt very useful and corrected my previous incorrect views on HTML and CSS. First, we can use visual Division to determine the meaning of the content. The search engine only sees the code. The search engine can only use tags to determine the meaning of the content. I have never paid much attention to search engines before, and now I

I think you have seen the word semantic for countless times, especially in some recruitment advertisements. In fact, I am also myself, but every time I see that it is copied by recruitment companies, in fact they do not know what semantics is, and do not value it at all. So I never took this thing seriously. However, when I see this word again recently, I think I should think about it. Write a blog record. 1. What is

HTML5 semantic tag practices (blog pages) and html5 Semantics A blog page is modeled after HTML5 + CSS3. The overall effect layout is as follows: The page layout is based on html5 elements. Therefore, it is important to familiarize yourself with HTML5 elements before you start, and then check whether its semantics is suitable for your layout. The HTML5 Structure It is very important that when writing HTML

Comments: B and I tags are not recommended in the current standard Web rules, or even opposed to use, because they are considered to be only "shown" in bold and italic, there is no "meaning ". Use the strong and em labels instead. The B and I tags are defined in the new HTML5 work draft as follows: The following are code snippets: B and I tags are not recommended in the current standard Web rules, it is even opposed to use because they are considered to be only "represented" in bold and italic,

improvement, but has been criticized for the following reasons:①: The user does not know whether NRV is really complete.②: Once the function becomes very complex, NRV will be difficult to implement. Optimization is performed when all named return instruction statements occur at the top level of the function.③:　　4. Copy constructor may be subject to an efficiency tax, such as the following code:　　X xx0 (1024x768= x (1014= (x)1014; // the actual process of xx0 is xx0. X::x (1024x768); // the actu

Best practices for returning objects within the c ++ 11 function using move Semantics In one sentence, return directly without any changes. After the c ++ 11 option is enabled, the Code returned through the function has not changed, but the move semantics has been used without the previous NRVO Compiler optimization technology. Note: The right-side reference rvalue reference is a temporary variable that no

The Apache Toolkit Common-lang has a very useful tool class for handling strings, one of which is stringescapeutils, a tool class that is added to the 2.3 version above, and it can be easily html,xml with The escape and reversal semantics of Java, but also the key string can be processed to prevent SQL injection, but it seems like common-lang3.0 after I looked like there is no way to deal with SQL statements, if you want to use the premise when the co

determines the exception we can capture if the throw of C + + is generated. Exceptions generated by the operating system, such as exceptions generated by the Windows SEH exception mechanism, cannot be captured. When testing, line1,line7,Line8 comments are canceled.Running the program, the " except 0" Exception still causes the program to stop. However, when the line4 input is changed to 2 o'clock, the exception ofC + + throw is Line7 captured.In the third step, we select "C + + SHE (/EHa)" and

the resource it points to is freed. Obviously, this is possible, but there is a more efficient way to swap x and temporary variables for pointers to resources or handles (handles), and then let the destructor of the TEMP variable deconstruct the resource of the original X. In other words, in this particular case, the right-hand side of the assigned value is the rvalue. We want the copy constructor to behave as follows: // [...] // Exchange M_presource and Rhs.m_presource // [...]This is
